sys.argv[1] is a string, so I assume that you meant to say that
the module named by argv[1] implements the correct interface.

try:

    factoryObject = __import__(factoryFile)
    print dir(factoryObject)

this should give you a list of the functions in the given module,
or an ImportError if it doesn't exist.

what did you try, and what happened ?  if at all possible, cut and
paste the code you tried (your examples above contained obvious
typos), and the actual error messages, so we don't have to guess.
