[correctanswer]

Python exercise:
Factorial recursive program , please provide screen shoot of the
code:
Implement the function factorial that
takes in an integer, checks that this integer is not negative (as
there is no factorial for negative numbers)
and recursively calculates and returns
the factorial of the input. Remember to implement your base case to
avoid infinity loops.
