because you print Hi! in the function. either just call: some_func() # NO print or in the function, RETURN "Hi!" instead of printing it. Then you can call: print(some_func())

The reason is: All python functions do return the value None except there is an explicit return statement written with a value other than None. The fact that None is returned, is NOT related with the print() statement in the function. if you replace this print statement like this: def some_func(): "hello" the function will return None anyway.

def somefunc(): return "Hi!" print(somefunc())
