4.14 import: A Deeper Look

You’ve imported modules (such as math and random) with a statement like:

import module_name

then accessed their features via each module’s name and a dot (.). Also, you’ve imported a specific identifier from a module (such as the decimal module’s Decimal type) with a statement like:

from module_name import identifier

then used that identifier without having to precede it with the module name and a dot (.).

Importing Multiple Identifiers from a Module

Using the from…import statement you can import a comma-separated list of identifiers from a module then use them in your code without having to precede them with the module name and a dot (.):

In [1]: from math import ceil, floor

In [2]: ceil(10.3)
Out[2]: 11
