NO ONE Taught You THIS About Type Hinting In Python 👑

This is a game changer for type hinting in #Python. #Shorts

I have used a lot of typehinting in my projects before, but I have never used a pipeline or the ellipses! Thanks this taught me a alot!

Tuples are immutable so you shouldn't be varying their length. You'll notice your editor won't complain if you define a list e.g. my_list: List[int] and put any number of ints into the list.

That first one is something i wish i knew 5 years ago when i was re writing a game client.

i never used ellipses yet but damn once i finish the general projects i'm gonna dive into that!

[greyhat_gaming]

That’s actually really useful! Thanks for sharing!

The point of the tuple is for you to define the shape. By doing a rest + union data type you're just trading correctness for "annoying"

[SaniSensei]

In usage, tuples are closer to dictionaries or (data)objects than to lists. A tuple typically represents some entity with differently typed values (like attributes). This becomes especially clear if you look at things like named tuples.

Dude these videos are SO good. Love these little sub minute tips.

I have been seeing this ellipses when reading API documentation sometimes but never got curious enough to search about it. I have used all other type hints except the tuple so this is actually helpful, thank you.

You are 100% correct no one taught me this.i myself learned it way before.

When C Dev's start coding in python 🤣🤣

[Joshua-spkd]

I could see wanting to use a tuple like a list like this because they’re immutable… but that’s it! Normally tuples are just 2 values

[RipazX]

Congratulations, you just created an int array... Tuple should have a definitive number of properties, otherwise what is the point of even having them....

[TheAndiKurz]

but a tuple should always be the same length so the way to fix this is use a

[cabbage-dev]

Python slowly that read like human language marketing

[cn-ml]

Thats not what tuples should be used for. At this point just use a list[t].

[RyanBarnes]

I feel it should be double asterisk instead of ellipsis. Like [**int]

[thetos]

I can see the argument about using the ellipsis as a shorthand for having repeated types, but as soon as you add that union, that starts screaming that need to use something else than a tuple (like a list) unless you definetely know your type has to be a tuple.

The whole point of tuple is to have typed collections of specific lengths and possibly heterogenous types, that are immutable, and that have the precision to tell which item has what type.

Great videos. Can you make one on the: variable: type = x notation? First time I've seen this!
