Flake8 Tidy Imports

A flake8 plugin that helps you write tidier imports.

• Free software: ISC license

Installation

Install from pip with:

pip install flake8-tidy-imports

It will then automatically be run as part of flake8; you can check it has been picked up with:

$ flake8 --version
2.4.1 (pep8: 1.7.0, pyflakes: 0.8.1, flake8-tidy-imports: 1.0.0, mccabe: 0.3.1) CPython 2.7.11 on Darwin

Options

banned-modules

An equals-delimited map of modules to messages to include about them, in rule I201 (see below). Whilst it can be passed on the commandline, it's much easier to configure it in your config file, such as setup.cfg - for example:

[flake8]
banned-modules = mock = Use unittest.mock!
                 urlparse = Use six.moves.urllib.parse!

Rules

Currently this plugin has two rules.

I200: Unnecessary import alias

Complains about unnecessary import aliasing of three forms:

• import foo as foo -> import foo
• import foo.bar as bar -> from foo import bar
• from foo import bar as bar -> from foo import bar

The message includes the suggested rewrite (which may not be correct at current), for example:

$ flake8 file.py
file.py:1:1: I200 Unnecessary import alias - rewrite as 'from foo import bar'.

I201: Banned module 'foo' imported

Complains about importing of banned modules. This might be useful when refactoring code, for example when moving from Python 2 to 3. By default there are no modules banned - you should configure them with banned-modules as described above in 'Options'.

The message includes a user-defined part that comes from the configuration. For example:

$ flake8 file.py
file.py:1:1: I201 Banned module 'mock' imported - Use unittest.mock instead.
