Module Namespaces

Modules are probably best understood as simply packages of names—i.e., places to define names you want to make visible to the rest of a system. Technically, modules usually correspond to files, and Python creates a module object to contain all the names assigned in a module file. But in simple terms, modules are just namespaces (places where names are created), and the names that live in a module are called its attributes. We’ll explore how all this works in this section.
