How to Avoid Import Conflicts When a Project Module Has the Same Name as a Standard Library Module?

Importing Standard Library Modules with Name Conflicts

Python script developers may encounter a common problem when a module in their project has the same name as a standard library module. This can cause import errors when attempting to access the standard library module.

Problem:

Many projects include a calendar module, but there's also a Calendar class in the standard library. Attempting to import the Calendar class using from calendar import Calendar imports from the project module instead, leading to error.

Solution:

To resolve this import conflict without renaming the project module, Python 2.5 and above offer the absolute_import feature. This feature ensures that the interpreter prioritizes imports from the standard library over project modules.

By adding the following line to the top of the script:

from __future__ import absolute_import

The script can then import the standard library's socket module, even if a socket.py file exists in the project:

from __future__ import absolute_import
import socket

In Python 3.x, this behavior is the default. When using Python 2.x, using absolute_import is recommended to avoid potential conflicts and ensure the correct modules are imported.
