Python's Magical Itertools Module

Показать описание

Have you been missing something magical in your life lately? Well in this video I am going to be introducing you to a magical module called Itertools! This module is magical because it provides built in functionality, specifically functions for creating integrators for efficient looping! I hope you enjoy the video and find it magical!

Comment before watching: Itertools has been a life-saver for a bunch of programming puzzles/challenges I've done recently, and I'm happy to see it get a moment in the spotlight!

YESSS I had a lecture on this 2 weeks ago but I forgot everything bc the lecturer rushed through it. So thankful for this video!

Hi Tim, I've purchased programming expert IO a week back. So far I'm hooked on it and the fact that the tests gives you a bit of creative freedom makes solving the challenges a lot more fun. Thanks for the effort you put into your craft. It really means a lot for people like me who cant afford to go back to university.

I have to say this was 'magical'. So many itertool fuctions I did not know about explained well. So many times I could have been using itertools rather than loops.

I work a lot with lists of nodes forming paths, knowing the pairwise function would have saved me a lot of headaches

Correction: All of python is magic, there's literally libraries for everything you can imagine

Great work... You're videos are sharp and keep getting sharper!

Tim I loved the Django Authentication tutorial you made yesterday, can make more Django project tutorials?

Another information that I don't know about Python. Very impressive that they are codes that make it more easier lol

Great video and walkthrough! Do you think one of the functions could be used as a part of a sudoku table-generator?

Great video Tim, I am buying the course

That looks extremely useful!

For the repeat and the chain (from_iterable) functions, I felt like they could be more easily achieved with comprehensions and simple list concatenation/appending.
All, of that if the objects to be repeated would not be large enough as to worry about memory management.
Is that the case or am I missing something?

For a moment, I thought that the chain.from_iterable function could have some extra functionality by maybe "unpacking" a list within a list.
But I tested and it was not the case:
chain.from_iterable_example([[1, 2, 3], [4, 5, 6], [[7, 8, 9]]])
prints:
[1, 2, 3, 4, 5, 6, [7, 8, 9]]

At 3:30, I think this is bad design. `for x in l` is usually interpreted as "for each item in l", a shorthand for a `for (int i = 0; i < l.size(); i++) {}` style loop. For me, coming from other languages, this would be an unexpected behaviour and I can imagine how it could lead to head-into-wall type bugs.
