Is it necessary for python recursive function to return a value??

We define a base case which returns a known value. But is it possible for any recursive function in python to not return any value and still do the recursion??

Yes You could have your base case print(something), then on the next line put return The return will stop the recursion without returning a value

Yes. You can have the function print a value or do some other action instead of return a value. It is only necessary that the input value signals the end of recursion. Edit: Oops, Somehow I overlapped with Rik Wittkopp's answer. It was not there at first when I viewed the question.
