I'm surprised nobody is protesting inequality in higher education. Students of prestigious universities have long had access to superior teaching and resources. Thereby increasing inequality between those who are admitted to these schools and those who are not.
@@whipit2404 I mean that's just reality, the parents of the students probably worked really hard to where they are now so they could provide a world-class education for their kids. Nothing to protest here, not getting into Harvard doesn't mean the end of the world but you can hope to either work harder then others to get in yourself or work hard so that your kids get into Harvard.
@@and_rotate69 I agree that paying well above 80k for these positions would attract and retain top talent in teaching, but I know at least some terrible professors that make over 6 figures. Watching this lecture almost made me wanna cry from how different the quality of some classes is in my university.
At 1:27:03 Works 3-4 times faster: q = request.args.get('q') words = [word for word in WORDS if word.startswith(q)] than: words = [word for word in WORDS if word.startswith(request.args.get('q'))]
Completed the CS50 Intro this May, just Lectures.... Big help in understanding the Lager concepts in order to better understand more niche UA-cam Videos and actually understanding what is happening and how, but also being able to troubleshoot and correct. -> Just started a project that requires Flask.
1:23:19 Probably the only wrong thing in this video. "Not sure what this does? Just run it!" lmao Other than that, the fact that you can get such a high-quality course online for free is unbelievable to me. I can assure you that the intro to CS course you take at your local college, the one you pay hundreds or thousands of dollars for does not come close to this.
At 1:30:15 I'd emphasize a list comprehension may be spread out over several lines for readability i.e. it doesn't literally have to all be on one line. Indenting within the square brackets won't matter to Python, but the reader might appreciate the added whitespace.
1:30:20 The instructor said that you cannot indent in a list comprehension (only use a list-comprehension when it fits within the screen). This is not true. Since the list comprehension is wrapped within a pair of brackets [ ], you can break the line anywhere you prefer to facilitate enhanced readability; and the list comprehension will work perfectly fine. Although, a really long list-comprehension that requires one to break down into multiple lines, may not be desirable, as future maintenance of such code could elicit unnecessary confusion. One of the tenets of writing better code is also the how less cryptic it is for future maintenance. Also, request.args.get("q") is getting called as many times as the number of words in WORDS variable. Perhaps a more resource-conserved approach will be this: q = request.args.get("q") words = [ word for word in WORDS if word.startswith(q) ]
Amazingly concise overview of the usefulness of flask and exactly what I was looking for. I thought it was a missed opportunity in the video to mention that list comprehension is done in C rather than for loops which are native python, making loops embedded in list comprehension orders of magnitude faster than regular for loops.
Forgetting the submit button at ~27 min made me crack up a bit haha. I probably made a thousand forms over the last 10 years, and always forget the freakin submit button on first try, to this day. xD
Wow it's so amazing,I found it interesting,I guess it's the right time I got it since am still learning it,,and can I get documentation for this course also,
@@rezzo_6fn659 You just need structure to study yourself. For example the freecodecamp curriculum privides a good visualization of what a good structure is. Html first, then Css, then javascript, then frameworks, libraries, API's...I would find good resources so you can go deeper on each one. Get some web developer bootcamp Udemy courses for example which also provide a structured path. Just advice from someone who started this journey 3 years ago and now I work doing this : )
58:00 didn't work for me of course but I changed some stuff around in the SMPT method host='ip address', port=port number and tried it and it just stopped halfway through loading...
Not trying to be the ‘smartguy’ but why would the person blur the whole url to hide it probably for security reasons at 16:00 and dont hide it from the tv behind the teacher at 16:00 for example?
As an advanced AI machine pretending to be a person he's quite convincing, except he keeps accidentally saying stuff like, "The humans figured this out."
The instructor used jsonify() in application.py but he didn't show the conversion of the JavaScript array returned into HTML elements in JavaScript section in index.html.
I haven't even got that far into the vid, I tried doing what he was doing in the current CS50 video for the course I paid for - and no matter what I do I can't get flask run to work I am seriously banging my head against a seemingly non-existent wall
@@Wildkomments then riddle me this. why does 'flask run' not work? I have had no issues with the class at all and now I'm basically brick walled on the last lesson. So frustrating -_________-

This man is a genius. He knows the art of teaching. No doubt! He is one of the best teacher in the world.
He has to
After all he has the pressure of teaching in so called world's number 1 university 😅
That's what you get from paying > 50k$/year

The preparation that went into this single lecture... He delivers it like a performance of a magician. Beautiful teaching
He blow my mind with this kind of teaching.
Many thanks for sharing, because i cannot afford a study at Harvard and this helped my a lot.
I am doing research about this topic for a long time and still couldn't find enough but this video covers everything I need! Thank you!
Which topic he actually covered? I didn't watched as I am thinking it is about building a basic flask app. Am I wrong?
David is really a brilliant instructor.
What a talented teacher he is!
LOL he's speaking like 1.5x by default
At 1:27:03
Works 3-4 times faster:
q = request.args.get('q')
words = [word for word in WORDS if word.startswith(q)]
than:
words = [word for word in WORDS if word.startswith(request.args.get('q'))]
No, it does not work any faster. They're both equivalent.
Yeah it will work faster as request.args.get('q') is being evaluated once. Good point. 👍

I can't explain how I'm grateful for the existence of this channel
Now I understand how a good teaching be like! Thanks Prof David
This’s a great teacher of Harvard! Thank Harvard’s for the free source.
He is one the best teacher in the world
I humbly submit Prof Art Dickenson from Cal Poly, SLO as the greatest of all time.
Just into the 4th minute of the lecture, and I have to say I love it.
I wish I had seen this last year, when I started to learn web development. This is soo good
Thank you for this incredible gift to the learning community!
Despite studying C Sharp and Kotlin, Python remains my favourite language.
u like the easy way, is normal
If I could have this man's clarity of thought

Better version than newer ones
I love how someone has blurred the web address in the Web Bar, yet forgot to do it in the Console LUL
Perfect teacher for the subject of programming. Thank you for posting this video
This playlist is a gem! Thanks a ton for making this available. Never had so much fun learning!!
Wow! The Harvard lecture is surprisingly, great! Thanks for posting these Harvard people. :)
Such an energetic teacher, very engaging. 👍

This is so great! Thanks Harvard for putting this online. What a source!
Thanks for this lectures. The professor is amazing
Absolutely stunning quality of lessons.
If you guys are looking for a HDR version. Check out CS50 2021 in HDR - Lecture 9 - Flask. Almost the same topic, just different year. Happy learning.
Excellent teaching
I wish this guy was the teacher at uni - i wouldnt have dropped out of software engineering.

David's amazing!
This man has amazing energy!
Brilliant speaker!
What a great teacher!
teacher is amazing...
Brilliant video! David Malan is insanely good.
Wow it's so amazing,I found it interesting,I guess it's the right time I got it since am still learning it,,and can I get documentation for this course also,
lecture not started yet but instructor is already in sweat
What a great teacher! I am happy for him because he must be paid really good working for Harvard since Harvard is such an expensive elitist school.
Thanks for the presentation
Amazing !!! I wish I was in the room with you, this is just perfect lesson!!!
Hi is amazing , teachers like that you get once in a lifetime if you are lucky !
This man is a genius
Yeah this guy knows how to teach!
Thanks David.
Satya Nadella blackmailed and active corrupt.
Excellent teacher.
amazing teacher and lecture
This guy teaches.
Awesome video. Where can i find the source code and notes of this 2018 course? Clickking the link leads me to 2020.

lol I forgot to give select a name of dorm
I'm kinda obsessed with coding, i barely sleep these days writing code.
Hlomani Job I’m trying to get into it. Looked at a few schools but they are expensive. Trying the university of UA-cam first
@@rezzo_6fn659 that's the cheapest University of all time
@Virasman Learning what exactly, coding or?

This guy condensed a 6 hour flask tutorial into 1hr 51min. Impressive lol.
I forgot I made this comment 2yrs ago
Génial!
Claro conciso evolutivo!
Gracias!!!
Great tutorial :)
Come on man, no-one wants a select list of 15+ hard-coded. Pass that badboy though WTForms as a python list. Haha
Man, you are best!
they are good but they shown the url in some sort of clips ....like in 27:15
Thanks for the video
Really,Amazing
Amazing teacher!
good tutorial, thanks.

@@himanshushukla787 omg they've surpassed us! 😅
Love it, thanks!
Wow they have their own IDE.

At 18:45 , how its even working before he changed the code?

Nice Explanation...
Sir please and please help me do a video on how to add a search 🔎 systems to the flask app
@14:35 flask hello world
give me access to the library
turn my file into a web app
listen to get requests on /
Great lecture! Thanks for free high quality material! 😊
Looking for Another video about data bases in Flask
Plz anyone tell about server login in email concept...And can I give any name??
wow, that's so cool
Am building my portfolio with flask
How come when he showed how to handle the arguments in the url did his hello david, hello world work before he type the code to make it work
My man keeps scrolling directly to addict, addictions 😂😂😂
Dangit, why didn't I go to Harvard? This prof rocks.
cuz u stoopid duh
@@Wildkomments then riddle me this. why does 'flask run' not work? I have had no issues with the class at all and now I'm basically brick walled on the last lesson. So frustrating -_________-
Yeah this David Malan guy is an okay teacher but he's definitely no Mr. Nagoor Babu sir.
nagoor babu has no flask class, correct?
dude, where is the green screen?!
why is jharvard3 blurred out in url?
Anyone had this error when running flask:
flask.cli.NoAppException: Could not import "application".
Thank you!
youth pastor energy
good video
I will tell my family that i study some dev courses in havard university hahah
Jesus how do you even find those libraries?
I didn't find full source code. In fact, I didn't find all directions, I found only CSV and .py files.
Once you add the students list I get an internal error. I cannot figure out what it is.
What Is the error code ??
