The pattern of creating an empty list, setting up a for loop, and then using several if-then clauses to determine which data should appear in the list can all be done in a single line in Python.

"Python cares about your sanity" love this xD
It's official! The Socratica Python Kickstarter was a success! Thank you to all of our supporters. Because of you, many more Python videos coming soon!! 💜🦉
I came over this video by chance and I am delighted by your ability to explain things as clearly as possible. Also I really appretiate great vocal. Thanks!
Looking forward to it!
4 months already, where is it🤷
You guys/girls/...are soooo goood. I came across by coincidence and i was absolutely shocked by this Peculiar way to explain it. You nail it!
"Python cares about your sanity", should be the motto of Python :D
Hahahahaha this makes my day, but honestly.... Why not
Actually, it doesn't compared to some of the other languages.
Ugh I'm the 70th like. Should have left it at 69

This comment is 4 years old and still gold. Thank you
Thanks man
Yeah , you’re definitely God sent…
You're the best. Seriously saved me 5 minutes of my life
Seriously, you guys have changed the way to teach. Its like I'm watching python scifi movie. You guys are rocking. Thank you for complete team for marking these beautiful tutorials
I absolutely cannot believe this channel exists. In-depth content presented so compellingly. Amazing
That's so kind of you to say, thank you! We're so glad you're watching. :)
OMG I just love the python series. I would pay cold hard cash for more in-depth computer science videos like this.
likewise
microwave ur cash b4 u give it to me
One of the best 'list comprehension' explanations I've seen.
Hello, Socratica! I am a Python self-taught and you are being a precious help in this learning process. I have faced some difficulties and several times I was about to give up but when this is almost happening there is something that suddenly gives me the courage to move on. Now I have the fortune to discover your magnificent channel and so continue learning Python with your wonderful tutorial. I feel that this is what I needed to fulfill my dream of becoming a programmer one day. When that happens I will give the name Socratica to the first program that I will develop in your honor. Thank you, my friends!
Thank you for this amazing comment. We are thrilled to play a small part in your journey! Stay the course, my friend.
So after 3 years of typing this comment, have you become a professional developer?
@@georgiosdoumas2446 I knew someone would ask this.
@@gauravnegi4312 lol
Everyone is self taught..
you are causing a revolution in the way people learn stuff.
I was having a difficult time understanding list comprehensions in the Udemy python course I'm taking, so I came here. This is my first time watching one of your videos, and it was sooo helpful. I particularly appreciated the use of an engaging, real-world example of list comprehensions involving tuples (i.e., movies from the year 2000). Quadruple points for the sci-fi aesthetic!
reading about list comprehension seemed complex and difficult to understand but Socratica cleared this topic in minutes....wow thannk you!
This is so great to hear!! 💜🦉
"It's now TIME for Python to SHINE, and save TIME with a single LINE"
The people making these videos are absolutely genius.
I have been teaching myself Python over a popular website, but their exercises are very few, and I find it hard to come up with ideas to practice on my own at this stage. This short video has taught me much more than what I have tried to learn for hours on that website! Kudos to Socratica!
Support what you love! Socratica has a Kickstarter to make more Python: bit.ly/PythonKickstarter
Just watched one video in this series and that made me to complete the whole series in one shot. It would be better if u upload more videos without taking much time. Awesome work.
this is my favorite coding tutorial of all :)
no trying to be an entertainer or showman, no blabbering about coworkers and their names and interests.
straight facts. and a sexy voice that reminds me of spymovies :)
Socratica has just revolutionized the learning experience; l'm indeed grateful to the team! You rock, Socratica!!
I was struggling with this all day until I saw this. Needless to say I will be coming back for more tutorials. thank you!
I'm strictly Javascript these days, but I am so happy I stumbled on your videos tonight. You're hilarious and enlightening. I have appended my name to your subscriber list.
Probably the best Python tutorial series on RUclips.
I love these videos! The information is top shelf, and the humor is extra EXTRA dry!
The double asterisk "**" is used for exponents because in general purpose programming the circumflex or caret "^" was already taken for "start of line" in file parsing, eg regex and for the bit-wise OR operator in C. Old languages didn't have any exp operator because it isn't/wasn't a primitive hardware operation in most CPUs thus exponentiation is provided via a libraries or custom functions.
More semantically speaking in various syntax that use the circumflex or caret "^" such as LaTex or MathJacks it actually represents a shift to superscript not necessarily exponentiation (in turn superscript when used with a number is what formally means exponent, but superscript is also used for sigma style sum notation and integral notations.)
In addition Python borrows heavily from C conventions and part of the advantage of Python is that it can interact with C more cleanly than many other languages. No need to reinvent the wheel or create mental syntax switching problems for the developer using both languages or simply using regex syntax.
wolfedog99. It borrowed from Fortran
Why oh why
This is way beyond me ....
I have been struggling with this topic for the last day or so. This video was very helpful in learning this concept, thank you for making it!
One of best channels.
This is a great video about list comprehensions.
I love your content :) .
I love using list comprehensions, so neat! :)
Hahaha.. append yourself to our list of subscribers. Definitely subscribing.
Here comes your new subscriber with list comprehension. Thank you, for such wonderful explanation.
Thank you, I`ve just deleted two whole functions and instead added three letters to my list comprehension! :D so happy about it!
This channel is a hidden gem, Since two days my productivity level is going higher n higher...
I am really impressed by this tutorial. I have ADD and it kept my attention lol. Thnk you for making this and I will now be using socratica for my coding studies.
Top notch video presentation and content. I absolutely love how your videos are able to hold my attention until the end.
This is a great video about list comprehensions. Python is a neat language!
Amazing video! I liked the futuristic-robot voice style
Best audio effect for the tutorials like this.awsome.
this style is so cool...and sarcastically funny at the same time!😂😂 the examples and explanations themselves are amazing, thank you guys for creating such an interesting video tutorial !!
Because of this tutorial, I earned a lot of respect in my company, everyone says my code is beautiful! Thank you!
I love these videos so much. Lots of information packed in small videos with out other unnecessary information. I want socraticas voice for my Google home too lol
Finally a video that explained all the details I needed! Thank you!
Excellent Videos, the story telling effect, the pauses, the content, everything.
Yo what is this gold the style is amazing!
Woooow,i feel like i am watching my favorite movie and learning my favorite subject with my favorite teacher at a time!
just wonderful.
my Question is how on earth i didn't watch this till now?
This is a phenomenal way of teaching and explaining things. I am in love with this channel :)
That was extremely informative, and the presentation just keeps it more interesting for good old scifi fans like myself 😊
gonna have to watch all your videos now
When I discovered your channel I already knew how to program in Python, but either way I saw all of your videos, because they're amazing and also funny. Well done and please keep up with your Python section.
One of best channels. Thanks for sharing the knowledge. Big Fan.
Finding this series has made me realize that every other channel that teaches Python is doing it wrong. This series is incredible, and I would be more than willing to buy these videos.
Starting this video, it felt kind of gimmicky
But I can't deny, this is an insanely good video with easy to understand and direct content
Fantastic work!
i love this. I am learning python all alone. This video has removed confusion from my head.
Your videos are awsome. FAST, CLEAR,UNDERSTANDABLE
Love this teaching style Lol.
30 seconds in and I like the channel already.
Keep them coming. This can't fail.
Incredibly well crafted video. Excellently explained. My congratulations, I didn't know your channel until now, but I'm really impressed, It's obvious you put a lot of thought an effort into your videos!
This is exactly what i was looking for. Thanks for the videos!
It's purely amazing how beautifully it is explained. I just subscribed to this channel. Congrats for making such beautiful and informative content and thank you!!
We're so glad you've found us! Thank you for your kind words. 💜🦉
Wow, I was looking a good video on this topic and even when this video got recommended I decided to ignore it first solely based on its thumbnail. Maybe my subconscious prejudices and stereotypes kicked in and guided me to avoid it, but when I overcame them and gave this video a chance I did not find it only very well made and informative but very creative and cool as well! Subscribed!
Awesome.Finally one best video I was looking for.
WOW! I just love this way of teaching!! You have got a new subscriber, Keep up the great work 😃
when i watch your video i get next level of energy, thank you socratica for your wonderful video
We need more of these videos...
It'll be really helpful if you can introduce analytics concepts with python.
Bless you people :)
Wow, cool episode, really. I'm so jobless at the moment but as soon as I'll get some income, be sure Socratica will be one of the good channels I'll support on Patreon. Can't wait to be able to do so!
Haha append yourselves to our list of subscribers, beautiful appended myself long ago keep up the good work
subscribed and likeddddd!! omg please dont stop making python Tutorials ever!!! keep it up! i learn and you guys make it so much interesting lol thank you..
Please upload more videos as soon as possible.It seems that you update your video nearly every two month.Already subscribed.
Hey @Socratica at 3:18 (Quadratic Reciprocity), it must be len(set(p_remainders)) = (p+1)/2 since you would have repeated elements in the list if you don't use set to discard the repeated remainders.
And thanks for the your awesome videos, you guys are doing a great job!
wowowowo this is my first video on your channel and i cannot control my hand to press the subscribe button :)
I thought I was really getting the hang of python until I got to list comprehensions. This video really helped A LOT though. Thanks!
Definitely helped me understand list comprehensions much better!
Teaching is an art and you possess this skill :)
This channel is so underrated it deserves more views and subscribers
Python cares about your sanity!
Simply clear as water. Perfect.
"append to our list of subscribers" THAT WAS HILARIOUS XDDDDDDDDDDDDD
You're so awesome that I created a Patreon account because of you guys! Thumbsup for the great quality videos!
That's amazing! Thank you so much for your support!! You have no idea how thrilled we were to get your message. :D
You guys do a brilliant job in democratising education. Many Thanks!
Thank you for your kind words and generous donation!
Thank you for explaining list comprehensions so clearly and simply. I thought they were pretentious when I didn't understand them, but now I see the value. Great video :D
This was amazing to read, thank you for letting us know!! 💜🦉
Love your teaching methods and keeps me entertained and focused. Hard to do with topics like this but your channel makes it look easy :)
great explanation, super visualization. Expecting videos on Decorators, pandas
Complex topics in a single video!!! Great.
The way you connect the concepts to real world, it's Simply Superb👌👌.
Congratulations! Amazing videos, keep going with this.
Some Client-Server sockets programming videos would be a great topic (:
You have made it very very interesting! Well done!
thanks for this video. just started learning python and was struggling with list comprehensions, but this helped me
A nested loop... in a single line of code. I'm in love :D
Codecademy skimps on details in some of their lessons. You've covered what they missed! Thank you so much.
This was great to hear - thanks for letting us know! 💜🦉
I personally think this style of teaching python is brilliant shame there is not more lately like this
We're halfway there. We still need your help! Support Socratica Python Kickstarter: bit.ly/PythonKickstarter
1:27 should be
[expr for val1 in collection1 *for* val2 in collection2]
Good spot, I fount it confusing as well
Exactly
yes, it can be also seen in the last example of the video
Never understood List comprehension in a better way before this :) Thanks
Absolutely awesome format!
Greatly explained. A lot of effort is put in this video
I tried learning the walrus operator last night, and tried applying it with the list comprehension examples given in this video. Its things like this that amaze me and make it fun to continue learning.
Example:
print( squares2 := [ i**2 for i in range(1,101) ] )
simply amazing... found this channel today.. awesome ... great work
We're so glad you've found us!! Thank you for your kind message. :)
Thank you very much! That was exactly what i needed! professional videos :) keep it up.
Thank you for the videos!! I love them. It helps me learn :)
Crystal clear and helpful ! As usual 1
Best video ever! It really teach how to save time while coding lists
