Question

Hi can some one point me some guidance, i pretend to pass the value of function schema to a variable that will be used as the argument step inside the range module.
i hope its clear .. sorry the newbie guys.
after some trials i got the edit fine.

import os
import sys


def schema(x):
    if x == 'M':
        step=1
    else:
        step=2
        return step

def main():
    left_start = 1
    left_end = 9
    sch = schema('M')

    range1= range(left_start,left_end,sch)
    if 2 in range1:
        print "In range"
    else:
        print "Missing in range"

if __name__ == '__main__':
    main()

Your code has a problem with indentation. The following:

def schema(x):
    if x == 'M':
        step=1
    else:
        step=2
        return step

should read

def schema(x):
    if x == 'M':
        step=1
    else:
        step=2
    return step

Otherwise, the function returns None when x == 'M'.

A more concise way to write that function is:

def schema(x):
    return 1 if x == 'M' else 2
