What is the use of '->' in a def statement in python [duplicate]

Question

Looking at the answer given here

example:

def md5_checksum_table(dir_name: str, suffix: str) -> {bytes: [str]}:

This is the first time I see -> used, and I do not understand what this does. I have tried to search in documenation, but failed to find the relevant description of this.

Can anyone explain to me what this is/does ?

I appreciate that this was a duplicate indeed, however I tried to search with multiple search strings on SO, and it did not reveal the post from 3.5 years ago. Thanks. — Edwin van Mierlo

It's a type hint, used to denote what type the method returns.
