The map, filter, and reduce functions simplify the job of working with lists. In this lesson, we show you how to use each function. If you also use lambda expressions, you can accomplish a great deal in a single line of code!

I LOVE YOU CAN I MARRY YOU.
What’s next?
Looks like these functions return lists in python 2 and iterables in python 3
Great series, more please !!
Ooh, bringing out python’s functional side. Sexy.
Wow you r good!
This is beautiful! Thanks Socrática!
Loved the cyberpunk style haha
HOW THE HECK I MISSED THIS CHANNEL ALL THIS TIME 🙁
Can you please do a “kivy” tutorial, your quality standards are very high and I really enjoy that 🙂
Love it!
These were almost removed from Python 3 in favor of list comprehensions. Guido didn’t like map, filter and reduce.
hahaha this is good tutorial !!! Sounds like CIA briefing 😛
I can’t stop thinking of GLaDOS while listening to this.
I fired Siri becoz of u…
one-liners?
You can be psychologist (professional-programmer) as a profession and a stand-up comedian (amateur-programmer) for extra income? (or was that the other way around)
As always !!! Brilliant thank you for the great educational videos .
Very useful tutorial, i have learned a lot from this video, thank you.
Please do a video on xml in python as well. These videos are priceless.
Thank you! keep them coming
Loving the hate for Fahrenheit 🙂 “How could this happen”
Third comment on a Socratica vid. Great vid, I like the pace. functools.reduce is indeed too confusing for me, Agree with Guido
What would be really kool… Is if text files were attached here containing the code in each lesson. Instead of typing each lesson in manually we could copy code blocks into a terminal (!) and then play. We could make slight changes to your code in a text file so we can experiment then move code blocks over over.
Thank you for those great videos.
wow just wow so easy way of explanation…….
Python should be a comedian because it is full of one liners.
Notification squad!
i need more video like this…………………………
Thank you for another great lesson! I’ve been using mapping lately and I love the way you explain it.
please make a series on machine learning tutorial i really want to learn machine learning but i cant find such as interactive and clear conceptual videos in you tube
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.
With the Map function, what do you do if the function you feed it has more than one argument? Do you simply add the additional parameters to the Map function?
Also I wonder if Java has an analogue to the Map function. Of course, Java does have a class by that name, but it’s a data structure instead.
Great series. Could you do a video on the Zip function? also more on Object Oriented Programming for Python 3
So reduce take two inputs at a time .. like the fibinocci and map just one input. Good one. Thanks a lot
Great job
So what’s the point of the function reduce? Is it faster than for loop?
wonderfully presented as always!
your illustrations always hit the nail on the head.
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.
Oh these are great.
these are seriously underrated videos……one of the best python tutorials……very nice
Beautiful and clever Woman as I like
Hey Socratica and Guido (if you see this) Beer is on me!
