Recursion. Recursion is. Recursion is hard.

A 'base case': a case in which the problem is trivially solved that is reached when a certain condition is satisfied.

A 'general case': all the other cases expressed as the solution of one or more smaller versions of itself.

def foo():
    if base_condition():
        return
    else:
        foo()
        return
