# Fill in the blanks to make the factorial function return the factorial of n. Then, print the first 10 factorials (from 0 to 9) with the corresponding number. Remember that the factorial of a number is defined as the product of an integer and all integers before it. For example, the factorial of five (5!) is equal to 1*2*3*4*5=120. Also recall that the factorial of zero (0!) is equal to 1.
def factorial(n):
    result = 1
    for x in range(1,n):
        result = result * x
    return result

for n in range(0,10):
    print(n, factorial(n+1))
