Modules

Modules encapsulate a set of features whether it be of the language or of third-party software.

There are multiple ways to import modules:

1. Import using the module name

import re

my_regex = re.compile("[0-9]+", re.I)

1. Access module using an alias

import matplotlib.pyplot as plt

1. Import specific values from the module

from matplotlib import pyplot as plt

Users should avoid importing modules using * to avoid overriding local variables.

from matplotlib import * #AVOID DOING THIS IF POSSIBLE!
