Today I found myself write a function that returns a tuple of list of list of strings (tuple[list[list[str]], list[list[str]]]). Wouldn’t it easier to read to write it like the following:

([[str]], [[str]])? 

Similarly for TypedDict, replace the following..

class Movie(TypedDict):
    name: str
    year: int

with 

{‘name’: str, ‘year’: int}

dict[str, int] will be {str: int} 

set[int] will be {int}. 

This is similar to the new proposed Callable alternative (i.e., (int, float) -> float) since it mimics the structure of a function. 

Also, Annotated[float, “seconds”] can be replaced with something like float #seconds indicating whatever comes after the hashtag is just extra information similar to a normal comment in the code. 

Imagine you could replace the following 

def func(d: dict[Annotated[str, “product label”], Annotated[list[float], “prices from 2000 to 2015”]])… 

With 

def func(d: {str # product label: [float] # prices from 2000 to 2015})…
