Importing modules with Python

I do not think you're talking about the installation. You have the documentation .

The default for importing in code is this:

from babel import *

This will import any Babel library. But you can choose just what matters:

from babel import Locale

Or you can import multiple members. And you can do it through a sub-module:

from babel.dates import format_date, format_datetime, format_time

In this case dates is a sub-module within the module babel .

All this I got on documentation . I think it's the best way to learn how to use the library.

If you want to study the Python module system at documentation is here . And about import .

Do with the reserved word import or from modulo import Classe . for example:

>>> from datetime import datetime
>>> datetime.now()
datetime.datetime(2015, 8, 6, 21, 57, 23, 947736)
>>> import os
>>> os.name
'posix'

See official documentation for python

In the case of Babel, the library page has an example

>>> from babel.dates import format_datetime
>>> print format_datetime(locale='ru_RU')
