IndentationError: unindent does not match any outer indentation level

Answer 1

Other posters are probably correct...there might be spaces mixed in with your tabs. Try doing a search & replace to replace all tabs with a few spaces.

Try this:

import sys

def Factorial(n): # return factorial

    result = 1

    for i in range (1,n):

        result = result * i

    print "factorial is ",result

    return result

print Factorial(10)
