Factorials Problem - OmarSinno - Sep-19-2017

3. Factorials.
Write a program factorials.py that prints the factorials of the odd numbers between 1 and 10. Your
program should contain a function factorial(n) that returns the factorial of an integer n.
Hint. Write and test the factorial(n) function before you use it in the loop.

I don't even know what Factorials are so help please?

Thanks to the internet I got this for now but I don't understand a line off it:

import sys
n = int(sys.argv[1])

def factorial(n):
	if n == 0:
		return 1
	else:
		return n* factorial(n-1)
		

for i in range(1,11):
	factorial(n)

Thank you in advance! Pray

If you try understanding the problem, maybe you can come up with a solution you understand.
Anything you write on your own will be better for learning purposes than copying code you don't understand at all.

Also, the example you found uses recursion, which is more advanced topic in programming. If you are just beginning, I would suggest using a loop to solve the problem instead.

Hint?

RE: Factorials Problem - OmarSinno - Sep-20-2017

def factorial(n):
    if n==0:
        return 1
    else:
        recurse = factorial(n-1)
        result = n*recurse
        return result

for n in range(11):
    if n%2 !=0:
        print(factorial(n))

Homework is done! :D
