Running an external program (executable) with parameters in python

Question

I am trying to automate a command line program.

The exe file takes one argument to run. For example:

ztac.exe <mode> (where mode options are safe, normal or debug).

To run in debug mode I simply type this in the command line:

C:\source>ztac debug

How do I write a Python program to run this ztac.exe file while taking the different modes as inputs?

Answer 1

program = 'ztac.exe'
arguments = ('safe', 'normal', 'debug')
argument = raw_input('Enter your argument: ')
if argument in arguments:
 subprocess.call([program, argument])
else:
 print('Illegal Argument')
