The return keyword is what informs the function if it should return a value or not. If no value is given to the return or no variable is assigned to be returned, then the return value is None
Function Return 0 in Python if assign a value is 0 and the function will end when the return keyword and value is reached.
Example Function Return 0 in Python
0 is not equal to None. However, in boolean context, they are different:-
def do_1(): return 0 def do_2(): return print(do_1(), do_1() == 0) print(do_2(), do_2() == 0)
A python function would return
0 either because of some computation:
def add_2_numbers(a,b): return a + b # 1 -1 would return 0
Why would a function end with “return 0” instead of “return” in python?
In Python, every function returns a return value, either implicitly or explicitly.
