Pass variables to system command

[likewtfster]

Hi!, im new here (obviously) but also to python and/or programming.
I am looking for information on how to use variables through start>run on windows.
My script, that works, is as follows

import glob, os
filetype = raw_input("File type ['*.*, *.txt']:")
directory = raw_input("Directory ['C:\Windows']:")
out = open("list.txt", "w")
files = glob.glob(os.path.join(directory, filetype))
for filename in files:
    out.write(filename + '\n')
 

but as i said before, i want to be able run the program when i am not at the computer, by using a task schedular for example, where the variables will need to be stated in the command.
Thanks for any help :D
