No. No, I did not.

Every time I think I have a good grasp on “pythonic” ways to do things, I discover something new like this. Love it.

You can create:
set compressions {_ for _ in _}
dict comprehensions {_:_ for _ in _}
list comprehensions [_ for _ in _]
generator comprehensions (_ for _ in _)
And in generator comprehensions you can remove a pair of parentheses to have something like this: tuple(_ for _ in _)

[rolandsz]

Imagine the surprise, when he learns about set comprehension and generator comprehension

This man is the master of lists. I can't say ive ever seen a video on any other topic

[snitox]

This is oddly relaxing to watch. I think this kind of educational content in what's missing.

[jglez]

Dude i saw this while implementing a long ass dictionary from a csv file and this video helped me do it so easily lol

[stonemannerie]

It's interesting that you had no idea that dict comprehensions exist but still feel qualified to offer a master course on python

[tsimafei_t]

Line 8, instead of list comprehension you can use map(len, names)

Comprehensions are seriously the only thing i like about Python, but i love them so much. They're one of the most plaintext self documenting features in any language.

I had a large coding project back in 2020, and that notation was key to my script working

For somebody who’s begun learning Python, these videos are really helpful!

[pareeks]

As a developer who has majorly worked on Java pre 8 and post 8 and JS, learning Python was fun and eye opener especially version 3

Dude, you make really nice coding videos. Your voice is smooth and the music makes it more interesting. Not some boring professor in monotone. Great job don't stop creating.

[MrVohveli]

I never knew I needed python shorts, but I do.

[jackeown]

There are also set and generator expressions! Python is awesome!

[dany_fg]

You can do it with basic iterable objects (list, dict and set)

[OfficialMazLi]

Wow that’s so helpful, i love the concept of list comprehension and was looking for something similar for dictionary, thanks a lot for sharing

[ismahelo]

Which theme are you using? Great tip btw!

[Soppybobs]

Comprehension is why I love Python, just a really clean way to map or filter or both to lists or dicts
