calling functions python

UpLink2008 · 08-29-2008, 12:34 AM

Right now I am going through some tutorials, This website in particular

http://www.sthurlow.com/python/lesson05/

And it talks about calling functions. What I am trying to do is make a simple function, Lets saying multiplying 5(70)

Then opening up a file and executing that program. I can't get it to work, I have searched the net to try to answer this question on my own, and all the information is advanced. Thanks alot guys!

For example I wrote a simple program

a = 0
while a < 10:
a = a + 1
print a

I named this program myprogram.py

Now what I want to do is open up another file, and tell that file to execute that program, How do I do that? Thanks!

I don't code in Python, so can't help with the technical things. Your post, however, doesn't include much useful information to be able to help with the problem.

Can you post some code? Is there something on that page that you don't understand?

What does "I can't get it to work" mean? What have you tried and what happens? Post error messages if appropriate.

In a shell script, e.g.

Code:

#!/bin/bash

./myprogram.py

Of course, this assumes that myprogram.py is in the current directory and has executable permissions.

In a Python program, you can use os.system, e.g.

Code:

#!/usr/bin/python

import os
os.system("./myprogram.py")

Again, myprogram.py will need executable permissions.
