Python: Annotated Assignment Statement

This might not seem as impressive as some other tricks but it's a new syntax that was introduced to Python in recent years and just good to be aware of.

Annotated assignments allow the coder to leave type hints in the code. These don't have any enforcing power at least not yet. It's still nice to be able to imply some type hints and definitely offers more options than only being able to comment regarding expected types of variables.

day: str = 'Monday'
print(day)
lst: list = [1,2,3,4]
print(lst)

Output:

Monday
[1, 2, 3, 4]

Or the same thing in a shorter way:

day= 'Monday' #str
print(day)
lst= [1,2,3,4] # list
print(lst)

Output:

Monday
[1, 2, 3, 4]
