- Learn Data Analysis with Python in this comprehensive tutorial for beginners, with exercises included!
NOTE: Check description for updated Notebook links.
Data Analysis has been around for a long time, but up until a few years ago, it was practiced using closed, expensive and limited tools like Excel or Tableau. Python, SQL and other open libraries have changed Data Analysis forever.
In this tutorial you'll learn the whole process of Data Analysis: reading data from multiple sources (CSVs, SQL, Excel, etc), processing them using NumPy and Pandas, visualize them using Matplotlib and Seaborn and clean and process it to create reports.
Additionally, we've included a thorough Jupyter Notebook tutorial, and a quick Python reference to refresh your programming skills.

The code links in the description have been updated to the content stored on GitHub.
you cant load the root folder into google collab. Therefore you need to load the exercises directly to the collab but that leads to an error if you want to try to load data e.g. sales_data.csv (' cannot open 'data/sales_data.csv' for reading: No such file or directory')
@@mellowbeatz93 check the path of the uploaded file . usually it is in a content folder .
please add persian subtitle😭😭😭🙏🙏🙏🙏
Yea, there's an error, does anyone have any advice on loading the exercise files ?
@@mellowbeatz93 if you navigate to your files directory, in colab, there is an option to copy the full file path name and from there you copy that, and paste it into your code like this (I saved mine with capital letters.)
sales = pd.read_csv(
'/SALES_DATA.CSV',
parse_dates=['Date'])

Thanks nan
I have a data science minor (with a Masters in Mech. Engineering). I work as a data scientist with focus on engine systems at the airlines. I'll tell you right now, this course was more informative than all the classes combined that I took in college. Santiago is one of the best you'll get, and also for free. This is truly a wonderful refresher.
I want to start this course. Is it still relevant in the end of 2023 or the information shared has become obsolete. Any insight will be highly appreciated brother.
ABSOLUTELY still relevant. Depending on where you work, you'll likely use Python or R, with occasional Excel uses as well. The important thing is the groundwork that is laid in this course. If you have a chance to take some probability and statistics classes at your school, do that. Also take your math classes seriously. Finally, Take an intro to data class somewhere online (easy to find), and you will likely know everything I know right now. I make about $150K/year so...@@TONYSTARK-ee5wy
As a data analyst in Maersk, I really appreciate this course in balancing between the technical foundations and actual executions! Most people only get to learn the codes without understanding the concepts, which are what separate workers from engineers!
Hi it seems like you were able to successfully complete the course did u have any troubles in accessing the sales file?
how much do you earn asa data analyst
With a name like that, how come you are not yet sanctioned by Biden?
I am 25 and I come from a strong pure and applied mathematical background, but I am a total newbie in programmation. I please have some questions:
1/ Are SQL, Python and R enough to get a permanent position as a Data Analyst / Data Scientist?
2/ How much time do I need to be able to manage and organize databases, and use them to produce statistical analysis and graphs?
3/ If I am hired, can the employer change his / her mind and ask me to code in other languages that were not written in my curriculum, such as C++ or Java?
@@vegetossgss1114 I could anwer your questions: I`m working in a data science team. In an entring possition you are generally hired as data analyst in the first place, even thought some business don`t make such diferences between data analyst and data scientists.
1- SQL knowledge is a must. You should be fine opting between R and Python. If you are starting and don`t know neither of them, I would reccomend Python, since it´s the most popular.
2- In most companies they already have data bases and you need to know how to write SQL queries to access the data and, after that, cleaning it with Python or R. If you are just trying things out, you only need data tables from websites such as kaggle. CSV or excel files.
3- It obviously deppends on the company, but that would be odd, since data analys/scientists are not meant to be "professional programmers".
If you have a strong mathematical background I think it will be quite easy for you to understand machine learinig algorithms in the future, which is something most people struggle with.

After the python course, I had to try different videos like numpy, pandas etc. This is way better!
i have reached the part where they r showing what we can do after this tutorial.. please help me out and let me know if i should practise more than the basic SQL before i continue this???
This is far better than many high-priced tutorial courses on the most popular MOOC platforms. I will forever keep this for future reference ❤❤
hi sorry please what's MOOC😢
I have been watching your course for 2 weeks and I can say this is the best guide I have ever seen. Thank you guys

hello, does this course have matplotlib, seaborn and all?
I am new to python. but I enjoyed this. If you are a newbie, dont focus on learning the syntax in this video. the best way to learn programming is to learn the functions first and then set aside sometime to work on your syntax skills. syntax overwhelms in the beginning. thank you for this. also loved your voice :)
This course is awesome ! The explanations are very clear and the teaching way is very fine. Thank you so much for all the hard work you put in making this !
i dont know how many comments down here are real, but i think this tutorial was wayyy to direct for a beginner... Numpy and Pandas are explained very well no doubts on that...the data cleaning part was very direct, no beginner will get a bit of it, reading external files section was Ok, Matplotlib was explained like everyone knows about the attributes since birth.
I am working as a data scientist from the past 4 years, i would not recommend this to anyone who is a beginner, except for the Intro , numpy , pandas and reading data from external sources section...
Completely agreed.
Sir can you please recommend me some tutorials as I am completely beginner and don't know anything about python.
But I have to learn atleast basics within this month. It's urgent. Please recommend me some videos.
I disagree, I'm a beginner and this is very straight forward. A beginner in programmatic data analysis should know what he's going to get into and this lecturer definitely has a great breakdown of that
I never could imagine to find such an invaluable complete course for FREE in UA-cam. I can not find words to appreciate.
Been looking forward to this course since the beginning of the year. It could not have come at a better time. Thank you very much!

Oh, thank you so much brothers, I have been waiting for a course like this from you guys, your channel has been so much helpful for me to improve my coding skills. You guys deserve to receive an award for this incredible service. Thanks again brothers, keep it up. 😘

You’re absolutely brilliant and generous for giving out this much information for all of us to learn, thank you!
i dont know a dang thing about programing ,just a little command prompt and thats it.. yet i actually understood what he was talking about. damn good teaching skills and communication skills .thank you.
2:08:09 The difference where the upper limit is included only seems to apply if you've defined your own index. It seems to work the same if you use the default numeric index.
This video was an unmitigated GODSEND! Thanks ever so much for posting it, Santiago! Since this has helped thousands of future DS folks out there (some of whom are struggling with a few of of these subjects like me), 1000000 karma points have been credited to your account :-)
A tremendous effort to go through data science topics. Extremely beneficial. Highly recommended and appriciation
I have completed whole tutorial I leant so much from this.. thanks free code camp and tutor..😍☺
Happy it helped :)
Best Data science course on the planet period
Cant imagine learning so good anywhere else :)
1:42:36 kindly note that the method np.arange is "arange" instead of "arrange", there is single 'r' instead
Good video. Note that not all exercise soulutions are correct. For instance, the exercise "Given the X numpy array, return True if any of its elements is zero" has an incorrect solution. Here is a correct (example) solution:
X = np.array([-1, 2, 0, -4, 5, 6, 0, 0, -9, 10])
print(not all(X))
Y = np.array([1,-5,3,7])
not all(Y)
I think you're also wrong in your code. The correct form is "np.any()" and not "not all()"
@@ahmadumeta4 I don't agree. I think that "np.any()" checks if any of its elements is NON-zero. But that was not the task.
@@Tommy_007 shouldn't that be "not any()" since it negates the condition and returns true if any of the elements is zero?
@@ahmadumeta4 No, "not any" is the same as "none" which is the same as "all are zero" which not what we want here. "Not all" (as I wrote) means that "at least one is not non-zero" which is the same as "at least one is zero" - and that is what we want.
Just seen the first few minutes and I seem to loke it. You have one of the most easy, quick and to the point explanations. Subscribed and willing to complete the video...
It's great to see so many thankfulness from every corner. It would be even better to see some gratitude transformed into donations. Some day this videos/courses will be over otherwise, no one survives only from free gratitude :)
Coming from Excel to Python i found this really helped. Thank you for helping me get my bearings.
Hi, am also coming from Excel to Python just like you
I started the course on July 15th and I will add a comment when I finish it
edit: I finished the course on August 2nd Considering that I know Python and spent seven days of time learning fast typing
is this video suitable for people who have no programming experience at all but want to look into using python for data analysis?
@@Invin_cibles programming skill isn't required. but basic python should be known
@@kartikhegde533 Thanks, I'm struggling to find the notebooks.ai demo or the interactive tutorial he's using, dont quite get the comment about google colab
@@Invin_cibles if you are using VS Code they have notebook option. In command palette type 'create new notebook' experiment for a couple of days. And watch a separate tutorial . There are plenty available
@@Invin_cibles You will need to learn the basics of python and the basics of statics for data analysis, and that will not take as many days as you think. It may take a couple of weeks. Just start, you'll get there at the end.

Data analysis is the process of exploring and analyzing large datasets to make predictions and boost data-driven decision-making. Data analytics allows us to collect, clean, and transform data to derive meaningful insights. It helps to answer questions, test hypotheses, or disprove theories.
Data analytics is used in most sectors of businesses. Here are some primary areas where data analytics does its magic:
Data analytics is used in the banking and e-commerce industries to detect fraudulent transactions.
The healthcare sector uses data analytics to improve patient health by detecting diseases before they happen. It is commonly used for cancer detection.
Data analytics finds its usage in inventory management to keep track of different items.
Logistics companies use data analytics to ensure faster delivery of products by optimizing vehicle routes.
Marketing professionals use analytics to reach out to the right customers and perform targeted marketing to increase ROI.
Data analytics can be used for city planning, to build smart cities.
Types of Data Analytics
Descriptive Analytics
Predictive Analytics

Amazing video, really really good, thank you Santiago for offering such a great free class online.
I liked it even from the beginning , you are doing a great effort to explain every detail. thank you
A word of advice for the guy teaching, please type the commands/codes yourself while explaining each line of code. You are just skimming what was already written and barely giving any time before scrolling down. Writing the code (prepare then read it from another screen or script) and explaining it will have a massive difference for your audience/students to understand. Teachers like blackboards over slideshows/pre-written materials to teach, because it helps the pace to train on it, is almost equal to the pace students understand.
Sure, the video gets a bit longer or maybe a lot but nothing beats understanding it better than a quick video where it's harder to understand.
Well said

I heard that we should focus on excel, sql skills for Data Analysis. People are now learning Python because it is getting popular.
So confused
@ifabulocitygirl that makes sense. Thanks.
Can you reply me because I have some confusion I want to clear it please help me
Excel is a good tool however it cannot deal with large data. Image doing all the analysis with even 5000 rows having to draw graph after graph onto different sheet. Excel gets very sluggish. With Python and their libraries with constant updates and support from the community, your good to go with even 1 million rows. Also like he said in the video, it gets cluster and tiring looking at the spreadsheets constantly, I find it quite distracting to do my analysis. SQL is good. I got no comments on that :)
See how awesome this course is 😎
what about a "freeMathCamp" or "freeLogicCamp" section?
Sooner or later you will have to use math and logic in programming.
Check out their "Mathematics" playlist.
This is a wonderful resource! Thank you!
Great course! The repo for part 7 doesn't exist, fyi
I've updated it, should be working now!
1:52:26 Taught a very complex topic in the easiest way.
The flow in this needs some work in my opinion. I've been using Pandas/Matplotlib for like a year and I still had a hard time following this. It's normal to hit high-level discussion before diving into specifics, but the way it's done here is not the best example on this channel. Doesn't help that the guy's pace of speech is not great. Slows down at all the wrong parts and rattles off important info.
I agree, he seems to start skimming more and more as you get deeper into the video which was disappointing..
Brilliant blue eyes and this course is awesome!!
If this is intended for people with no knowledge of Python, it's hard to follow. I don't get how to write commands or what the basic principles are, so it seems to me by 'beginners' you meant people who know some python and want to dive into data analysis using it.
A beginner's course to Python is meant for people who are new to Python. Once you want to use Python for a specific goal, there is no reason to repeat the basics of Python since you can learn that in their Python course.
Vraiment
Great contents. The speaker knows exactly what he's talking about and has great deal of detail knowledge about python and various libraries. Thank you for sharing.
I'm just wondering if sharing the fundamentals and ground level details (numpy memory) could have been a separate course all together and this one could have just focused on data analysis, may be....
please help. where can i find the dataset " btc-market-price"?
Excellent course, you can download the material and practice and check your knowledge. Thank Freecode and Santiago!
NO algo expert,NOOO..i dont want to be a software developer at google.
why not, Google is a big company

The best tutorial in youtube
Thanks for this tutorial. Can anyone tell me where can I find these csv files ?
Very thorough video, does a great job of explaining intricate concepts in a simple way.
where can i find the file csv thx
Dear Santiago! Great thanks releasing the valuable video! You have rescued me from confusion in data science
54:37 is when he starts to actually teach. Just saying.
Well, I was _teaching_ how to use Jupyter Notebooks before, some people might not know how they work.
You shouldnt discourage my brothet
This is insane effort. Thank you, thank you !!!!
This course isn't good. The instructor moves like a bullet train between topics. Fonts are too small for Mac book Air. The section on data cleaning is very confusing. I had to pause this video and follow other videos on data cleaning. The flow of topics is also very jarring.
Why isn't data cleaning the second topic after 'Introduction'? I tried my best but gave up after 3 hours or so.
Really appreciate this material. Helped me a lot with my dissertation.
You know, you have to tell us about import requests. This isn't something python beginners automatically know exists. This is a big problem with all these "learn code" courses. You're not walking us through line by line and describing what the code does or when, why, how we should use it. It's great to see what python "can" do, but we need to know when to do what with it.
These courses are the equivalent of telling us that numbers exist, giving us 0-9, showing that numbers can be added and such, and then expecting us to go out into the real world and apply them to geometry without ever providing the intermediary steps.
Your perspective is enlightening. Similar to a book that's an exemplar. "Adapting with Aging" by Various Authors
Quite disappointed by the teaching structure. Nothing hands on, just endless narrations, code executions and assumptions. It is far from beginner friendly and seems rushed all the time. Not sure if the comments are legitimate because, I can't be the only one struggling to process and grasp the plenty methods and arguments while the course progresses. Started off well, but completely sunk from Numpys down.
I almost got discouraged by your comment but I decided to follow the video comprehensively
The best way I think to understand the tutorial is by practicing the codes available via the links in the description and trying the exercises after every lesson. Although, you might end up spending more than 4 hours on the video but i believe it's a good sacrifice for knowledge.
That aside, I agree with you that the tutorial is not 100% beginner friendly. You must have some basic knowledge of Python before even thinking about using Python for Data Analysis. If you don't, it's better to watch a tutorial on general Python programming for beginners before this.
It's for beginners in data analysis, not python or programming in general
@@abioyeorimadegun7851 do you recommended it?
@@andredias5061the title says "DATA ANALYSIS WITH *PYTHON*", it's a clickbait and totally confusing( I'm a total noob in coding or analytics)
@@prashansingh8861with python meaning you are supposed to to know python already. Come on guys
It is thousand times better than CS courses at college!!
I just want to marry you guys~ love the course!!
coz of course marry
generally super! Now I'm in a great mood for the whole day! thank you!:)
Title of video: Data Analysis with Python.
Spends no time coding, just reading websites. 😠
Actually data analysis involve less coding more depends on analytical part
This is more of a video overview with external exercises (linked in the show more section). It seems useful but I'm not sure it works as a UA-cam vid. I wish it went through everything in real-time rather than having to do exercises on one's own without any visual feedback.
Thanks bud, this is really helping!
All in all, thanks for providing a free course for us :)
Just started the course, Jupyter went great, I decided to use Jupyter lab instead of Jupyter Notebooks.
Went through Numpy lecture, seemed good.
Now I'm at Numpy Excercises, where I had trouble loading the notebook and I ran into a couple of errors in the Numpy Excercise problems.
If i run into more, i'll try to post them here for other people by editing the comment. Can't promise anything though.
Possible error list:
Numpy Excercises - Logical operations:
Given the X numpy array, return True if any of its elements is zero (prosing a change to non zero here) because np.any() is a test for true (non zero) elements, and therefore the wrong answer.
ALL I CAN SAY..... YOU ARE AWESOME..............................!
Awesome!! TQVM. 4 hours is not too long.
Thank you, Thank you, Thank you ❤🎉🙌
I was looking for some tutorial some tells me both basics and helps me start with analysis. Thank you so much for this video. Its very helpful
Is that enough to study in data analysis?
I advise you always keep the explained fragment in the center of the screen. Subtitles cover it at the bottom of the screen
I'm new to data analysis and this video shows up. Appericiate it :)
