Import¶

import m¶

• searches for a module named m,

• creates a module object for that module, and

• assigns the module object to the variable

A module is anything that Python considers a module and knows how to create a module object for, includeing things like:

• Python files,

• directories and

• built-in modules written in C

A module object is a Python object that acts as a namespace for the module's names. The names are stored in the module object's dictionary (available as m.dict), so we can access them as attributes.

Regular packages¶

If a directory contains a __init__.py file, it's considered to be a regular package.

Namespace packages¶

• does not need the __init__.py file

• can place contents of a package across multiple locations
