How to use python type hinting?

In this video, I will show you how to use type hints by example. We are going to put hinting to work, by actually adding type hints to some code I have prepared for us. We will learn the basics of Python's type system as well as some more advanced topics like Union and Generics.

Great tutorial, needed a quick refresher!

[ryman]

Thank you! For me this it way more accessible and digestible than the documentation.

[Saitama-urlq]

now that is how you explain 100s of videos on youtube couldnt pull this one off, well done chief!

9:20 this is basically like C++ templates...
I like the way you edit your videos, nice production value.

[pkavenger]

wow, what a coincidence I was looking to use type hinting inside my Binary search tree and I found this video. This is exactly what I was looking for.

[AakashNarang]

Great Stuff. Concise, clear and with proper explanation. And yes you covered a lot in 18 minutes 👌🏼👍🏼

[DuarteMolha]

Thank you so much for this video.

I was looking for what looked like a eternity on how to solve the forward referencing (I now know what to call it :))

Hands down the most useful python video I have seen in a while

Hello again, glad to see you still make some quality content. Didn't know about type hinting in Python, even when I write in it all the time. Thanks!

[johnmccrary]

Thanks for the video, I remember back when python added type hints but I haven't really looked at the typing module before seeing this

[ringyring]

8:01 the funniest moment I've seen in a dev video. 🤣

[DreySF]

A very nice pace and good explanation. Gut gemacht.

[vnikolayev]

Nice and educative video format, liked it a lot!

[drooten]

This was really good. Good enough to subscribe to.

3:25 it would be great if you can make more videos on data structures

[theradlectures]

Wow, echt super, danke! Have used typescript? Why is it that typescript is discussed so often, but so many people are ignorant of pythons type system?

[sillytechy]

Hi please can you make a playlist for all the data-structure implementation using python

[DevOpsDirective]

Do you have any heuristics or "Rules of Thumb" that you follow for when typing is worth the effort?

For example:
"Always use types no matter what!"

OR

"Add types in function signatures for functions being called from outside the file they are defined in"

[prashantlawhatre]

4:15, I think, we can now use left: ClassVar[Any] = 10, right? or 'ClassVar[Opional[Any]]'?

[pkavenger]

Can you also make a video on NewType because I dont actually get it where can we use it. I have read a lot about it in documentation but still I dont get what is its use and where it should be used. TypeVar and NewType are quite similar.

[chandrakantthangapalam]

when can we have a data structures and algo video out eagerly waiting for it
