Unmatched Python Function

Question

I need to write a void function that contains three arguments (dictionary, string, string) in python. Obviously python does not have a void function, but is there a way I can make a function in python that acts like a void function in C, C ++ or Java?

Answer 1

Since Python is dynamically typed, and you do not specify the type of the return value when defining the function, you can return anything with any type that includes None , which is the return value by default (when you do not return anything, the function actually returns None in bottom of function)

Also a simple return equivalent to return None if you want to do this in the middle of a function.

EDIT: forgot to mention: if you use the yield keyword in a function (even if this line is never executed), the story changes, and this is no longer a normal function, this is a generator ...

Answer 2

You can either add return None to the bottom of the function, or simply omit the return .
