Python tricks: Type hints and static type checking

[austinhaider]

I've learned everything I know about Python from YouTube and your videos are some of the best I've come across. I appreciate the amount of detail you go into about every topic; keep it up!

that is the clearest and simplest explanation for type hints. thank you man.

[arachnid]

Thanks for explaining this. Your explanation was very deep and clear. I was a little perplexed with this concept.

[francescofaccia]

Good job Seb. Very well explained. Clear and synthetic!

[raspreetsingh]

An amazing explanation dude, I was having some difficulty understanding the callable type hints but you did such an amazing job of ELI5ing it. Thanks a lot :) and keep the great content coming

[nelsonmacy]

Very clear and to the point. Appreciate

[barulli]

everything is clearly explained! cheers!

Nice video - thank you! Maybe you also could be interested in Pyadaaah, which provides runtime (!) type AND range checking?

[justchary]

Man, you good! Thanks for explanation.

I really enjoyed it. Very usefull video . Thank you so much for this

[RodrigoStuchi]

👏 👏 👏 👏, very nice explanations, thank you!!

Your explanation is amazing, and your outfit is stunning..

PHP has real type hints. I was surprised to find out that Python’s interpreter ignores them.

Except, Negative number have factorials :)
And float have too... :)

[lazypunk]

Anyone else getting an error in factorial function while doing mypy type checking. It says return type got "None" expected "int", which actually makes sense because we are returning NOne for a certain case when we have mentioned that return type is int. Why is that error not popping up for you? Seems mypy got some smarter updates since

[flyingsquirrel]

Is None still always accepted by mypy? And if yes, why are they not using the "Optional" class from the typing module for that?

interesting video, thanks pal, go ahead.

Hi,
For the first program I'm getting "Incompatible return value type (got "None", expected "int")" how to deal with it ?

[javierbosch]

I'd love to get a list of your atom Python Packages that you are using. the REPL, autocomplete, etc. packages

[Serotonindude]

optional static typing... :D
am i wrong, or is it like:
1) if static typing would have saved you... of course, you didn't use it
2) if i take my time to give proper type hints... why does the runtime not care at all? i may optionally type check it with another program...

i don't know... feels like do it right all the time or just leave it
