how to create python modal forms

[hshivaraj]

I need to know how codeA.py would call these (either codeB.py, codeC.py etc.)

There are many ways how you can call another python module. It depends what your trying to achieve from calling an another module. Calling in using os.system or by using multiprocessing module do all the same things.

The question to ask, what is the intention of calling those module? What do you want from the calling module to return. That is, are you expecting some value in codeA from codeB and are expecting to process the return value in codeA?

This is what I need to do as the form Can be closed down etc while codeB.py or codeC.py is still active.

If this case, I think there's serious design issue here.
