What does cls() function do inside a class method?

Question

Today I\'m viewing another\'s code, and saw this:

class A(B): 
    # Omitted bulk of irrelevant code in the class

    def __init__(self, uid=None):
        self         


        

Answer 1

It's a class factory.

Essentially it the same as calling:

o = A(uid)

cls in def get(...): is A.
