You can always import yourself and use getattr on that module.

in file "mytest.py":

def foo():
    print "foo called"

def call_by_name(name, *args, **kwargs):
    import mytest

    f = getattr(mytest, "foo")
    f(*args,  **kwargs)

if __name__ == "__main__":
    call_by_name('foo')



Alternatively you can import __main__ if you are always going to be
running directly from that file.
