Answer 2

#The return should be after while loop:
def factorial(n):
p=1
i=1
while i<=n:
p *= i
i += 1
return p
print(factorial(int(input())))

Answer 3

Check out recursion in python core course

Answer 4

You can solve this in one of two ways: with recursion, or with loops. Unless I'm mistaken though, the question wants you to do it with recursion.

Well, the factorial of a number n is the product of whole numbers from n to 1. So, when you define your recursive function, it has to be something like this:

def func(n=1):
if(n > 1):
return func(n - 1) * n
return 1
