Global Variable from a different file Python

is that possible to set variable in different file ?

So I have two different files somewhat like this..

tes1.py

import test2
st = 'a'
def main():
  mis = input('puts: ')
  print tes2.set(mis)
main()

tes2.py

def set(object):
  pics = ['''
  %s
  1st
  '''%st,
  '''
  %s
  2nd
  ''']
  return pics[object]

and i execute tes1.py and issued an error:

NameError: global name 'st' is not defined

thanks for the respond

A few tips:

• Wrap your main() function in a if __name__ == '__main__' block. It prevents imported modules from executing code that should not be run when being imported. I usually do away with main() completely and just write all my main code in the if block.
• object is a built-in type. Don’t name things object. Also set, as that is a type as well.
• Global variables are discouraged, as there is always a way to make global variables into parameters (unless your global variables are constants, which is fine).

Here’s how I would do it:

test1.py:

import test2

if __name__ == '__main__':
  st = 'a'
  mis = input('puts: ')

  print tes2.rename_me_set(st, mis)

test2.py:

def rename_me_set(st, obj):
  pics = ['''
  %s
  1st
  ''' % st,
  '''
  %s
  2nd
  ''']

  return pics[obj]
