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

Question

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??

Answer 1

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

Answer 2

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.
