python calling python

[G. David Kuhlman]

Either (1) you are making this harder than it needs to be or (2)
you are trying to do something different from what you describe. 
If (1), then try:

import myProgram2
myProgram2.main(arg1, arg2, ...)

As a general guide, you may want to use the 

    "if __name__ == '__main':
        main()

idiom at the bottom of each of your modules.  That way any of your
modules can be run from the command line (e.g. for testing
purposes) or can be imported (so that you can use functions and
classes in them).

An additional suggestion -- Use the 'main()' function to grab
command line arguments and then pass them as arguments to another
function, say myJob(arg1, arg2, ...), that does the real work. Then
other Python code can call myJob directly.
