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 am currently attending a university master in data science. These videos are 100 times Better than the slides I got from my professor. Clear and Easy to apply. Thank you
Wonderful stuff. Sharp, professional and lively. The humorous delivery takes the edge off. At the same time, the presentation is carefully scripted to teach clearly and efficiently. No hesitations, no mistakes, no confusion. Just fast and pleasant learning. The code animation is easy on the eyes and so is she!
list comprehension is also a good option instead of map function: areas_lst = [ area(r) for r in radii ] also for filter: filtered_lst = [ d for d in data if d > avg ]
I was about to point out the same thing. You can much more cleanly combine both with an expresion like filtered_areas_list = [area(r) for r in radii if r > minimum ] and for the efficiency of an iterator, just swap the [] with () to make it a generator comprehension filtered_areas_iter =(area(r) for r in radii if r > minimum ) list and generator comprehensions are also far more intuitive for anyone who encounters them in the wild without knowing about them beforehand

I have never seen tutorials this amazing. Its like I traveled back in time 30-40 years when people still made sense - could think and communicate. I enjoyed these so much. Thank you for all the hard work and long hours you guys put into this series. You are hands down the best! Can't wait to see the next one.
I generally don't comment but I am really amazed by this awesome video is. One word Awesome.... !! loved the way the concept was taught and delivered...
At this very moment, you are the most engaging python teacher on TH-cam. Goes down mainly to the tone and style/theme and covering so much in one small video.
Just started studying python a month ago, after almost 20 years of java programming language and I've just fallen in love with it. Great programming language. Very cool and attractive presentations Socratica.
Wow... Yesterday I found this channel and I can honestly write I've had difficulties with map, filter and reduce; especially knowing when to use them. EVERYTHING fell in place with this short video... amazing.
@@Socratica You are so welcome! I've watched some more videos this evening and you're making all subjects crystal clear in a very unique way. Keep up the good work! :)
These videos are evidence that anything can be explained in a clear, concise and easy to understand way. It really shows how silly knowledge gatekeeping is at the university and institutional level.
Wow! I can't believe you are dis'ing the reduce function. The reduce function is the general form for more specific functional ideas.. A solid understanding of reduce is essential for any modern programmer.
Extremely well done series. The best way to learn in my opinion. Short, to the point, engaging, code examples and awesome jokes. Using a one-liner one-liner joke... beautiful!
It took me 12 years to find this channel. The algorithm never recommended me this channel. I stumbled upon this channel by entering, filter map lazy, in the search bar. Because... I was doing some exercises with map() and filter() and noticed the following code had unexpected results: num_list_4 = [2, 3, 6, 8, 9, 12, 15, 17] threevens = filter(lambda x : not x%3, num_list_4) sqrs = map(lambda x : x*x, threevens) print(num_list_4) #print(list(threevens)) print(list(sqrs)) The commented out line causes the sqrs list to be empty. And that's why I'm here.
This stuff is great. Before going for the heavy artillery, it's also useful to first consider list/dict comprehensions, but map,filter,reduce are great tools for the toolbox.
Just so people know, this is in python 3. In python 2.7, map returns a list itself and not a generator so there is no need to do list(map(fn, list_of_ele)) rather map(fn, list_of_ele) returns the final list.
Awesome. I was learning at Coursera applied data science with python. And had doubts in maps and lambda. Came across your video. Very creative and also very nice explanation with real life example. Excellent. Please make more playlists. Thank you so much
Python ain’t the only comedian on this channel! 😉 I do love map and filter, but after they took reduce away I found myself leaning more towards just using list comprehensions. I usually want a list anyway. I do agree with the philosophy of providing a single way to do something, and map and filter are extra viewed that way.
personally I absolutely hate the whole 'outer space' theme BuT there is the best available information available on this channel which makes it one of the best out there so thank you. much appreciated!
I loved the explanation. Thank you. But if is was there in person watching, i would NEVER, raise my hand if had some doubt. This woman talking give me chills.
I have been practising Python three for a while now but what I would really like to see is some videos on project ideas or scenarios to build on using Python. This would be great from practice and learning.
Excelent video! I like the style and the presentation character too. And a tasty last line python joke. Congratulations. It would had been gorgeous to have a teacher like her in my college years. Hahahaha!!!
Awesome. The reduce example also works with text. ",".join(mylist) is commonly used, but reduce gives you more flexibility and in my opinion is more elegant, especially if you're combining multiple operations/functions.
Awesome scripts. I am seeing this usefull for converting ips to binary and build a subnet calculator to confirm our firewall configurations are correct. Thank you so much for the work you've done on this.
Your course is awesome! Thank you. Im going through sololearns python courses and for each section, whatever the subject is, i come to your vids for further thorough explanation of whats being taught. I Appreciate your efforts more than words can express.

Smile pls
@Stimpy&Ren ok
No, Thank you for making such amazing videos
chiere.....
Python should be a comedian because it is full of one liners.
lol
A Map, a Filter, and a Reduce walk into a compiler... >.< Ugh! Obviously I should NOT be a comedian, lol.
1:40 "If brevity is the soul of wit, then python is in a class by itself"
The language itself was named after monty python
Still too long. What in python you write in 1 line, in R you do in couple of symbols
I am currently attending a university master in data science. These videos are 100 times Better than the slides I got from my professor. Clear and Easy to apply. Thank you
Hi are u also learning machine learning...??
I am going to subscribe for this comment since I am starting my master's in Data Science in a week 😂😂 thanks BTW
Wonderful stuff. Sharp, professional and lively. The humorous delivery takes the edge off. At the same time, the presentation is carefully scripted to teach clearly and efficiently. No hesitations, no mistakes, no confusion. Just fast and pleasant learning. The code animation is easy on the eyes and so is she!
It's a master piece.
a masterpiece of a comment. clear and precise points. a subtle hint of hitting on the instructor.
@@Sra4825 she is worth it!
You must be the best communicator of all time! Thanks.
list comprehension is also a good option instead of map function:
areas_lst = [ area(r) for r in radii ]
also for filter:
filtered_lst = [ d for d in data if d > avg ]
I was also going to comment that these functions are mostly deprecated because of list comprehension and generator expressions.
I was about to point out the same thing. You can much more cleanly combine both with an expresion like
filtered_areas_list = [area(r) for r in radii if r > minimum ]
and for the efficiency of an iterator, just swap the [] with () to make it a generator comprehension
filtered_areas_iter =(area(r) for r in radii if r > minimum )
list and generator comprehensions are also far more intuitive for anyone who encounters them in the wild without knowing about them beforehand
More readable!
And faster than map filter and reduce.
same here

Moment I heard the last line. Paused. Liked. Subscribed. Turned on notification. Too good.
Support what you love! Socratica has a Kickstarter to make more Python: bit.ly/PythonKickstarter
I can't stop thinking of GLaDOS while listening to this.
At this very moment, you are the most engaging python teacher on TH-cam. Goes down mainly to the tone and style/theme and covering so much in one small video.
From a Haskell programmer: Great introduction! In addition, script provides a nice, subtle sense of humor. Ms. Castro has superb enunciation.
You are in a class by yourself Socratica! The way you teach is simply superb!
Till now I haven't seen a video being posted like this, great with differences that making this playlist and channel different from others, keep it up
Thank you for your kind and encouraging message!! 💜🦉
Just started studying python a month ago, after almost 20 years of java programming language and I've just fallen in love with it.
Great programming language.
Very cool and attractive presentations Socratica.
This is by far the most clear explanation of filter/map/reduce! Thank you very much!
Loving the hate for Fahrenheit :) "How could this happen"
pranjal86able We do not know. 😂
Like my first Professor in electrical engineering, she always told us to keep to keep it clean and metric ^^
I was looking for this comment.
That's why your Elect Engineering teacher likes Peter the Meter Man!
Sigh, I wish US would use metric system, make life so much easier.
Wow... Yesterday I found this channel and I can honestly write I've had difficulties with map, filter and reduce; especially knowing when to use them. EVERYTHING fell in place with this short video... amazing.
This was so great to hear - thank you for telling us! It really helps us get motivated to make more videos! 💜🦉
@@Socratica You are so welcome! I've watched some more videos this evening and you're making all subjects crystal clear in a very unique way. Keep up the good work! :)
This is by far the best explanation of map, filter & reduce in Python ever.
Why is Socratica so underrated. Why, oh why!?
lol I just found this channel
Didnt ever know that tutorials could be made this engaging. Brilliant.
What a beauty... Programming languages always surprise me with its deep. Thank you for clear explanation!
You are great finally, someone teaches python with enthusiasm, instead of the sleepy attitude , BTW i really like the themes you use Great job
this is the funniest python tutorial i've heard in a while....
"How could this happen? I do not know"
Easily my favorite video.
Best map,filter,reduce explanation i've seen for any language! Thx!
This is the only tutorial I've seen so far with this quality of editing, like, WHOAH!!!!
These Python tutorials of Socratica are simply the best!!! 👏🏻👏🏻👏🏻
I am addicted to your channel. Such wonderful delivery and the humour is priceless 😊
Thanks!
Such a kind gesture - thank you so much!! We really do appreciate your support. 💜🦉
these are seriously underrated videos......one of the best python tutorials......very nice
Socratica team is a unique blend of technology, teaching, wit and dialog delivery.
These are a few of our favourite things!! 💜🦉
"Python should be a comedian because it's full of one liners" - subscribed
Your presentation is just out of this world.
These videos are evidence that anything can be explained in a clear, concise and easy to understand way. It really shows how silly knowledge gatekeeping is at the university and institutional level.
First video I've ever watched on this channel. Kinda spooky but very engaging.
Wow! I can't believe you are dis'ing the reduce function. The reduce function is the general form for more specific functional ideas.. A solid understanding of reduce is essential for any modern programmer.
> Beautiful is better than ugly [...]
python -c 'import this'
Extremely well done series. The best way to learn in my opinion. Short, to the point, engaging, code examples and awesome jokes. Using a one-liner one-liner joke... beautiful!
You deserve much more attention! Those video are clear, interesting and have a great knowledge transfer.
hahaha this is good tutorial !!! Sounds like CIA briefing :P
Austin p.b maybe it is lol
how do you know what a cia briefing sounds like Mr pb ?
It took me 12 years to find this channel. The algorithm never recommended me this channel. I stumbled upon this channel by entering, filter map lazy, in the search bar. Because... I was doing some exercises with map() and filter() and noticed the following code had unexpected results:
num_list_4 = [2, 3, 6, 8, 9, 12, 15, 17]
threevens = filter(lambda x : not x%3, num_list_4)
sqrs = map(lambda x : x*x, threevens)
print(num_list_4)
#print(list(threevens))
print(list(sqrs))
The commented out line causes the sqrs list to be empty. And that's why I'm here.
The "multiplier" lambda expression is already defined in Python -> "import operator as op"
Therefore the reduce call is : "reduce(op.mul, data)"
Thanks so much for this video!
I've just explored this channel and I loved it!
This is the most entertaining python tutorial I have seen lol, but at the same time, I got what I need. Thank you!
I love the Command and Conquer / Westwood Studios vibe of these videos. I love post apocalyptic learning.
Love the Halo/Matrix-esque aesthetic of this channel 🖤
If brevity is the soul of wit then python is a class by itself.
"Wow", this channel needs to be praised for its intellectual content.
Wow I'm loving Python and Socratica more and more with each video - thanks Socratica!
your illustrations always hit the nail on the head.
This stuff is great. Before going for the heavy artillery, it's also useful to first consider list/dict comprehensions, but map,filter,reduce are great tools for the toolbox.
Ok. You just got a sub. These are hilarious while at the same time quite informational and compact. Well done.
Just so people know, this is in python 3.
In python 2.7, map returns a list itself and not a generator so there is no need to do list(map(fn, list_of_ele)) rather map(fn, list_of_ele) returns the final list.
[fn(el) for el in list_of_ele]
There's no reason to ever use map in 2.7
And people who still use python 2.7 should go back to Jurassic age.
Liked the clip. 'Friend Face.' Instructive as always with useful and practical information and approaches.
A keen sence of dread lurking around you... ...must complete the class, for your own survival!
Love the approach! Inta Sub!
I very much love the correct plural usage form of radius :)
Awesome. I was learning at Coursera applied data science with python. And had doubts in maps and lambda. Came across your video. Very creative and also very nice explanation with real life example. Excellent. Please make more playlists. Thank you so much
I kinda like your approach very much, must've been so much effort put in this.
Watching ur videos brings a lot of pleasure and understanding of some moments, thx for ur work!
This is a python masterclass...even the jokes are efficient. great job and more please!
"Python should be a comedian because it is full of one-liners." haha You got me there.!!
Nice innovative idea than other tutorials to explain.... Loved it
3:09 - "Do not forgot your jacket if you are visiting Argentina" ahaha that was gold!
Python ain’t the only comedian on this channel! 😉 I do love map and filter, but after they took reduce away I found myself leaning more towards just using list comprehensions. I usually want a list anyway. I do agree with the philosophy of providing a single way to do something, and map and filter are extra viewed that way.
Great (and funny) vid👍🏾
Thats amazing fully qualitative stuff with both professional and some humor thanks for the content
Very crisp, clear and efficient !
After watching this, I want to buy a projector first, and tune in on this channel from video 1. Great work👍
Very good EXPLANATION
List is a python constructor
List,earlier list.Append(list1 or lamba to earlier list)
Map to reduced list
So reduce take two inputs at a time .. like the fibinocci and map just one input. Good one. Thanks a lot
personally I absolutely hate the whole 'outer space' theme BuT there is the best available information available on this channel which makes it one of the best out there so thank you. much appreciated!
I love the voice and speaking rhythm. Very informative videos.
I loved the explanation. Thank you. But if is was there in person watching, i would NEVER, raise my hand if had some doubt. This woman talking give me chills.
I feel like I'm watching a missing debrief from a cartoon about spies from the 90s
"we live to serve the user"
in all my life I've never felt like the disposable tool I'm feeling right now .-.
Did you like it?
I have been practising Python three for a while now but what I would really like to see is some videos on project ideas or scenarios to build on using Python. This would be great from practice and learning.
wonderfully presented as always!

Thank you for the video. I am grateful for your time and contribution. Kind regards, Akira.
Great tutorial, concise and simple
Please do a video on xml in python as well. These videos are priceless.
She compared xml to json in a previous video and basically said to hell with xml... for it's complexity....
Your course is awesome! Thank you. Im going through sololearns python courses and for each section, whatever the subject is, i come to your vids for further thorough explanation of whats being taught. I Appreciate your efforts more than words can express.
Very charming and delightful narrative
Your explanations are the best! Thanks for the help.
Socratica, you are missing a golden opportunity by not having merchandise from this series.
Fantastic, per usual. Thank you. Awesome presentations with flawless, logical, and efficient, instruction and code.
You made python sound like a detective story,very entertaining and useful!
The course is very simple... But the art direction is sooooo cool
A unique style of python concept explanation , very different from other python learning TH-cam videos . Nice :)
Interesting approach style-wise. I like it.
First time I watch your video I think u r awesome
Captivating while teaching me what I needed to learn. Finally I know I'm gonna master Python soon!
Wow... finally understood... thanks and subscribed
