Positional only function parameters

Hi, great presentation of a lot of core concepts !

I think positional only parameters may have a place in your cheatsheet

translate

你好，我很喜欢这个备忘录，我之前看到另外一个备忘录 https://perso.limsi.fr/pointal/python:memento
我想能否也提供一个翻译的方式，提供给大家提交翻译的文档？

Hello, I really like this memo, I saw another memo https://perso.limsi.fr/pointal/python:memento before
I wonder if you can also provide a translation method for everyone to submit translated documents?

Regular Expression \d

I felt that your project is wonderful. I created this issue because I thought I could contribute even a little.

About

Python's regex can implements meta characters, but we have to use carefully when using \d, because it includes all of Unicode characters which are in category Nd.
regex - Regular Expression
List of Unicode Characters included group Nd

\d's behavior

ascii mode => [0-9]
non ascii mode => all of characters which in category Nd

For Unicode (str) patterns:
Matches any Unicode decimal digit (that is, any character in Unicode character category [Nd]). This includes [0-9], and also many other digit characters.
Matches [0-9] if the ASCII flag is used.

regex - Regular Expression

Why I created this

I think people who is not accustomed to regex can think it only includes [0-9] by default. However we have to set ascii flag. This is significant when creating validation for user id or password.

Reccomendation

Before

\d Decimal digit

After

\d Matches any characters in Unicode Number, decimal digit category. This include not only [0-9].

NamedTuple notes.

This is an awesome cheet-sheet Very helpful, thank you. I don't think what I've found is a mistake, but maybe a small way to add more info.

The notes on named Tuple call collections.namedtuple. There is a newer typed version of NamedTuple under typing.NamedTuple. I am having a hard time finding the docs.python page for you but I found the dev-docs page for it. Might be worth a look.

Async and Await keywords missing

The async and await keywords should be added to the keyword section.

`bool(self)` dunder method should mention the `not` operator

Yep

Cheatsheet does not distinguish members of related mutable and immutable types

For instance under Set, methods like discard and pop do not apply to the immutable (frozenset) version. I'm not sure how best to distinguish this, but it could be helpful to delineate their differences.
