In Python, 'variable' is a synonym for name and identifier,'

An object can have 0 to many names attached to it. An object can also be 
a member of 0 to many collections.

Modules, classes, and functions have 'definition name' strings attached 
to them as their .__name__ attribute. This attribute is used to display 
the 'value' of these objects, as in
 >>> def f(): pass

 >>> f
<function f at 0x00F05420>

The __name__ attribute is also used in the idiom
 >>> if __name__ == '__main__': print("I am the main module")

I am the main module

to determine if a module is being run as the main module as imported 
into another module.
