Is This Code Ok? How Can I Avoid Using Global Variables?

[DeaD_EyE]

You can return everything:

def foo():
    return {}, 'Foo', 42, 1337.13, [], ()

Implicit all arguments are packed into a tuple.
Afterwards you can unpack the objects.

Dict, String, Integer, Float, List, Tuple = foo()

Now the names refer to the objects.
