i have been working on a excelworkbook having 8 worksheet and i m performing operations on data nd want to place dataframe in the 6 sheet in place of its data .but everytime i do all other sheets gets vanished nd a single gets get formed with the dataframe .plzz help me in appending df into an existing excel
I know this is 5 years old but I learned more about using Pandas from this one video than all the other videos ive watched on the topic combined! Just awesome! Thank you!
This video was super helpful, thank you Keith! In case anyone gets to the end of this video, around 48:00, Keith talks about the groupby operator and starts to go over the section "Aggregate Statistic using Groupby (Sum, Mean Counting)". You might run into errors due something that changed after Pandas version 2.0.0. Instead of writing: df.groupby(["Type 1"]).mean() Try writing: df.groupby(["Type 1"]).mean(numeric_only=True) After version 2.0.0 the numeric_only value was changed to False versus True as it's default, causing errors such as "can not convert strings". Hope this is helpful, have a good one!
Hi Keith - not sure you will read this but wanted to sincerely thank you for this tutorial. 3 years ago this was the first python video I ever watched after graduating from unrelated subject. Today I'm typing this from a business class lounge at JFK, on my way to London where I just got a job as a quant developer at a hedge fund, building pricing models and infra for trading. Worked hard for this but if not for your videos I could be at a very different place. Thank you from the bottom of my heart, your work means a lot to many people. Cheers!
Wasted an hour watching a completely useless video on pandas, didn't understand a thing...... Then found this pure gold of a video, it really helped me a lot. Why didn't I click it earlier............
thanks for useful video If anybody have a problem with calculating the mean of Type 1 grouped data, use this: df= pd.read_csv('modified.csv') df.groupby(['Type 1']).mean(numeric_only=True) instand of this: df= pd.read_csv('modified.csv') df.groupby(['Type 1']).mean() That way, it won't include string-type data in the mean and sum functions.
Great video! One of the best pandas tutorials I've seen. I have one comment though. When you run (at 40:00) df.loc[df['Name'].str.contains('Mega')]) You are actually including Meganium in this filter, even though it is not a Mega pokemon. So, one needs to include a space after Mega, such as: df.loc[df['Name'].str.contains('Mega ')]) One can see that this makes a difference because when you run len(df.loc[df['Name'].str.contains('Mega')])) and len(df.loc[df['Name'].str.contains('Mega ')])), to know the number of rows, there are two distinct outputs (respectively 49 and 48)
There is something to the way Keith teaches that keeps me coming back. Besides being a good teacher and utilizing techniques which help people grasp the material quickly and remember for long time, he sends forth a wave of positivism. He is such a positive, energetic person. Thanks for sharing your knowledge. May it grow and enable you to bless more people with it.
Keith You are more than a teacher. Your level of simplicity in explaining Python in details is out of the moon. Keep up the good work. Your video is always my “go to” any time. Again, thanks a lot for using your skills as a blessing to people around the world.
Coming from the R environment, I must say this is an excellent tutorial to learn about Pandas. I'm very happy to learn that the tools I use in R for data management can be implemented in a similar way in Python. Thanks for taking the time to put this together! Great job.
@@manan-543 I think Python is far more general and overall can do a lot more, but in my field, packages associated with statistical models are far more abundant in R than in Python. For example, I'm not sure Python comes even close to R for the implementation of Bayesian hierarchical models, GLMMs, GAMMs, etc. Also, methods papers often publish packages in R, so it seems to remain the default for statistics. Until the statisticians start switching in large numbers I'm not sure this is gonna change anytime soon; and when it does, it probably will be Julia, not Python.
53:30 you can use .size() to get the count of each Pokemon type instead of adding a new column. It would look like this: df.groupby(['Type 1']).size() Great tutorial!!
Excellent!! I like the way you organize the videos on different topics and functions of working with data. Please make more videos on how to work data science in Python. E.g. Statistical analysis (descriptive statistics, t-test, linear regression) or data processing tutorial (like what we do in SQL).
Awesome tutorial! One advice I'd have for any python developers is to get in practice of working within virtual environments. Really helps to avoid conflicts when you're working on a project which may require some older versions of a library but your other projects may require latest ones, stuff like that.
Bro I started a data science internship in the beggining of the Year, we use a lot of pandas and you are saving my life from day 1. Thanks again, you are a god send! Subbed on both channels, cheers!
Between jobs for the first time in decades I wanted to learn data science using software other than just Excel and Access. Your video was well explained and frankly better than anything else I have seen so far involving Python and Pandas. Thank you for a job well done.
Saved my day! I started learning Pandas, but when I missed several months during circumstances and this video about basics helped me quick comeback. Thank you!
I have been learning python and using pandas for about 3 months now and done innumerable searches on the internet with questions regarding use of specific statements and coding. I wished I had come across your video earlier! You are a born teacher and know how to layout and explain complex terms and concepts. How can someone that looks so young have such a strong grasp on presentation and user needs? The concepts you explain are the same things I have sought information on for 3 months but all in one place and succinctly explained. Thank you for all your work.

Thank you so much for posting this! I have a test in Python soon, so I've been watching this for a review. You explain everything so well and make it easy to follow. I also like how the data was from Pokémon - it makes it more relatable.
Hey dude, love this video by the way but I have a question, can this data be used for machine learning? I have my exams coming up where I have to find a dataset to make predictions and stuff. Are these pokemon cards, do they have label and features if you understand what i'm talking about? Any help would be greatly appreaciated. Thanks in advance.
Awesome tutorial Keith, I learnt a lot by following your hour long tutorial. Created a new notebook instead of using the GIT version as it doesn't show what happens before you commented the code.
This video helped my massively! Been learning through online python courses with people trying to act and saying unnatural jokes, but your video felt super natural and easy to watch. Many thanks!
In the chunksize section, you pick a well-documented bad practice, namely calling pd.concat inside a for loop. As the loop runs repeatedly, this operation becomes more and more expensive (because new_df gets longer and longer). Per the pandas documentation, the better approach is to append each df to a list and then pd.concat the list elements just once, after the for loop.
You break down all the details in a way that I can't believe this is for free. Very high quality stuff. I was up and running with this library in short order
This is an amazing tutorial! Please keep publishing like this. very well explained! I would love to see about matplotlib, numpy and if you can get inside machine learning
Wow man! Holy smokes that was such an amazing breakdown. I came into this knowing nothing about Pandas and now I want to get back to work with my personal data! Thank you so so so so much. I’m off to find the documentation!
Ok I've been learning Pandas for a while now, over many different sources, and this one video has shown me much more helpful little hints and tips than all of the other material I've looked at previously!!! Thannnnnk you! Please do more Pandas stuff as this has been so awesome =]
The best tutorial I have seen so far on data analytics. I now see how python/pandas helps in data analytics. Thank you very much for making and sharing this video.
Day 1 on my journey to learn data analysis with python, this vid and kaggle's free pandas course is just what i needed to give me more motivation to keep learning.
Great video to get people up and running. It took me two hours to watch, take notes, and test out some examples. I feel like this was time very well spent. Thank you for this.
Very simple yet comprehensive tutorial on Pandas. You had my attention throughout. I do use Pandas for data analytics along with numpy. That said I learnt quite a few tips and tricks. Thank you for sharing your knowledge. Way to go Keith! Liked and subscribed.
this is an excellent tutorial, especially the filtering/conditional changes section. I have always loved how google sheets has built in queries, and I wanted to be able to do a lot of the same things using pandas. This essentially gave me all of the power I needed! thanks!
Gold medal bro, I was searching extensively for a good data science resource and reddit just sent me to random coursera/edx courses that used to be free but don't appear to be anymore. Your content is highly organized, extremely concise, and well thought out. There is a reason that only .01% of the votes are downvotes. THANK YOU!
Wow, thanks for this tutorial. I'm starting on python and took a course of udemy, but it was confusing, with your explanations many doubts are cleared up. Thanks Keith:)
Came here after watching your "Real World Data Science Tasks with Python" video and I didn't expect there are still things I don't know with Pandas. Thank you! Liked and subscribed.
Omgeeeeee!!!! Thank you so much!!! I've searched sooooo many videos trying to help with the delimiter problem I've had (i didn't know that was the problem) and you're the ONLY one I've found that even mentions it!!! 🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾
WOW! This was just what I have been looking for! Fantastic tutorial! You explained everything very well and clear from start to finish. Best Pandas tutorial on youtube for sure! Thanks man :)
This was great man. Even in 2020. Only thing and suggestion. Do not change a cell when you are elaborating on a new feature. Just click a new cell down and elaborate. Because then in the jupyter notebook you will see all the variations. If you change it it won't save in the jupyter notebook. I'm very happy with this tutorial. You break it down easily. I'm new to pandas and python and this has helped me a lot with pandas.
I've been looking for a good pandas and python video for quite sometime now. I have to say that this is really amazing. You've explained it so well that a beginner like me could easily understand. Great job and thank you. Can't wait for more videos. (if possible, matplotlib)
27:15 It seems that the dataframe got scrambled up a bit there, most likely from having the cell running multiple times. Even when there was an error message, it appears that either the Total or the Legendary column was moved to the left of HP. Upon running the cell again (with the corrected version?) it calculated a new Total adding the previous values and generating corrupted results.
Thank you so much for your time and effort. This is the best python tutorial I have watched. Straight forward and well organized. I appreciate the time stamps.
Pandas is incredible. The stuff you can do with it is mind blowing. For example I've got product data in a CSV, and prices in another. The prices depend on values in the product name. Pandas can easily do this without writing for loops.
A fellow man of culture I see. Funny enough as I was multi-tasking through Python tutorial videos while playing x2 Switch SwSh pokemon. I'm nearly at the end of your tutorial video and so far, good job on this. Keep it up!
This was such a great introduction to pandas and on DataFrame. This is exactly what I was looking for. Since I hadn't previously downloaded pandas onto my mac, and didn't feel like installing anaconda either, I was running into some troubles installing pandas with just "pip install pandas" so I thought I would include the instructions as to how I did it. simply do: pip install pandas --user If nose and tornado aren’t downloaded do: pip install nose --user then pip install tornado --user (nose needs to be installed first) then terminal also suggested I add it to my path, so I did: sudo nano /etc/paths add the path at the end of the file do ^X and then Y then hit enter
What the hell, I imagined this topic in afternoon and video recommended after only few hours. And the shocking fact I didn't even searched about this topic from many days.
This was genuinly so helpful, thank you! I am mostly through a data science course and have been struggling to figure out actual applications for the information I have learned. This was excellent!

thanks it helped a lot...can't understand the error while all the values are numreic already
so is it got updated now, since you can only perform the method on int or float columns ...

I've been looking for a good pandas and python video for quite sometime now. I have to say that this is really amazing. You've explained it so well that a beginner like me could easily understand. Great job and thank you. Can't wait for more videos. (if possible, matplotlib)
27:15 It seems that the dataframe got scrambled up a bit there, most likely from having the cell running multiple times. Even when there was an error message, it appears that either the Total or the Legendary column was moved to the left of HP. Upon running the cell again (with the corrected version?) it calculated a new Total adding the previous values and generating corrupted results.
Comprehensive, perfectly paced.... Lovely tutorial!
I am a retired software guy, enjoying your videos, thanks for these! You are making me almost want to go back to work again.
literally one the most useful videos on pandas ever
Thank you so much for your time and effort. This is the best python tutorial I have watched. Straight forward and well organized. I appreciate the time stamps.
Thank you, Keith, for making this super helpful tutorial. You're a great teacher!
F for "MEGAnium" that got filtered out while being old school Poke 😂
Great course! Looking forward to learn more from you!
I fixed it by writing "Mega " in the code.
Apart from maybe silencing your phone while doing the tutorial, you are definately the man for the job!! Great work and VERY helpful!!!
You are the GOAT. Your explanations using Pokemon makes so much sense.
This is an extremely usefull tutorial. You explain so good bro. Thank you very much. Like and subscribed. Hugs.
Excellent tutorial; exactly what I was looking for. Liked and subbed. Thank you for sharing your expertise.
Thank you Keith for this video, absolutely amazing and valuable for many! THANK YOU!
Glad you found it helpful! :)
Pandas is incredible. The stuff you can do with it is mind blowing. For example I've got product data in a CSV, and prices in another. The prices depend on values in the product name. Pandas can easily do this without writing for loops.
You've just got me 30% of my whole assignment. Thanks dude
Makes me want to play the old Emerald games again, wonderful tutorial, keep them coming
Awesome video Keith! I'm a beginner programmer but your explanation is super clear! Thanks for the videos:)

You can also just write the code: df.groupby(['Type 1']).count()['Name']
That way, you don't have to add the count column.
I just realized this a Keith video I haven't even watched it yet and I already know it's gonna be good! My data science guru
A fellow man of culture I see. Funny enough as I was multi-tasking through Python tutorial videos while playing x2 Switch SwSh pokemon. I'm nearly at the end of your tutorial video and so far, good job on this. Keep it up!
This was such a great introduction to pandas and on DataFrame. This is exactly what I was looking for.
Since I hadn't previously downloaded pandas onto my mac, and didn't feel like installing anaconda either, I was running into some troubles installing pandas with just "pip install pandas" so I thought I would include the instructions as to how I did it.
simply do:
pip install pandas --user
If nose and tornado aren’t downloaded do:
pip install nose --user then pip install tornado --user (nose needs to be installed first)
then terminal also suggested I add it to my path, so I did:
sudo nano /etc/paths
add the path at the end of the file
do ^X and then Y then hit enter
What the hell, I imagined this topic in afternoon and video recommended after only few hours. And the shocking fact I didn't even searched about this topic from many days.
thast AI at work
finally.. a new video... I was waiting for a Long Time😍😋
it's been a year since I first saw this video
pandas has been the best thing to happen to me and this is where it all started
thank you Keith
That's awesome, really happy to hear that this video had an impact on you. You are very welcome :)
@@KeithGalli I'm seriously impressed that you replied to both of my comments
Take care and stay safe
One of the best programming tutorials ever made. seriuosly.
"It's not super important that you know about a DataFrame"? That's one of the main objects in pandas, I'd say its highly important.
When I start making money with these knowledge, I'll give you some share!
I loved the fact you used pokemon as data set it was fun learning I could also check
my knowledge about pokemon hahha Love love
This was genuinly so helpful, thank you! I am mostly through a data science course and have been struggling to figure out actual applications for the information I have learned. This was excellent!
Glad you found it helpful!!
Thanks, Keith - Best Pandas overview yet!
I learned so much, thank you. Then at the end...that music tho. I lost it! LOL! Did not see it coming.
This tutorial helped me alot. Thank you so much!
Great job dude.
I think taking the Pokémon data set makes this tutorial so much fun. Loved it.
Keith you're the best.
This is one of the best videos on pandas.
