If the import of run succeeds, you can find out where the module run is installed on your system by adding a print statement: import run print run module:, run That will show you where Python is finding the run module. And, if the import statement is failing, then you are likely to need to install something in order to execute that sample code. Once you have found the run module, ...

The class code for TestPanel preceded the code which I copied above. The object win clearly is instantiated. I understand how the if__name__==’__main__’ only runs when this program file is executed. But, I can’t find any reference to a module run and I don’t see how the “run.main([“ line casues the “runTest(“ function to run. I've never heard of this module. Where did this code come from? Have you tried the code? Either run is some builtin I haven't heard of, or the code is in some library/turorial that defines a custom module. -Luke What am I missing? Thanks for any help.

Re: [Tutor] Main program confusion
It's wxpython demo's code. It's necessary to have the run.py in the same path, to make it run, and usually also some other files. -- Tom, http://www.vscripts.net I've never heard of this module.

Hazlett, Les wrote: Dave, Thanks for the guidance. I followed your advice and learned the following: import run print run module:, run run module: module 'run' from 'C:\Python25\Lib\idlelib\run.pyc' I don't think that is the correct run.py. Luke, I found this mystery main program in the extensive demos in \wsPython2.8 Docs and Demos\demo\. It is used throughout the demo code – in every demo sample I have looked at. There is a run.py in the demo folder, that is the one you get when you run the demos. Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Hazlett, Les wrote: Thanks Kent, Yes, there is a run.py in the demo folder. I is the one that runs and not the one in the Python25 lib. So, I tried to see if I could find it if I previously imported everything that the code imports. It didn’t – see below: IDLE 1.2 import wx import sys,os import run print run module, run run module module 'run' from 'C:\Python25\Lib\idlelib\run.pyc' This has been a good lesson in my learning process. Thanks everyone. It's not finding it because you're running your code in the directory that IDLE is located in! If you start a Python interpreter in the Demo directory, you will be able to find the file you need. Python searches the current working directory for modules first before it does anything else. Coincidentally, Idle has a module named 'run' and since the interpreter's current working directory is IDLE's directory, it imports that one. Try using the commands import os os.chdir(Path/To/Demo/Directory) and import the module. You should get the correct one, then.
