Please read the documentation for inspect.getargvalues:

"""
inspect.getargvalues(frame)

    Get information about arguments passed into a particular frame. A
tuple of four things is returned: (args, varargs, varkw, locals). args
is a list of the argument names (it may contain nested lists). varargs
and varkw are the names of the * and ** arguments or None. locals is
the locals dictionary of the given frame.

    Changed in version 2.6: Returns a named tuple ArgInfo(args,
varargs, keywords, locals).
"""

HTH,
Daniel
