Question about namespaces and import. How to avoid calling os.system

[Jeff Epler]

In main.py, execfile("gen.py")

or

In gen.py, have something like
    from __main__ import env_params

or

In main.py, have something like
    import __builtins__; __builtins__.env_params = env_params

or

call a function in the gen.py with env_params as a parameter
    import gen
    gen.do(env_params)
