pylint-pycharm

GitHub (pre-)release Travis GitHub license Waffle.io - Columns and their card count Stars

This plugin provides both real-time and on-demand scanning of Python files with Pylint from within PyCharm/IDEA.

Pylint is a Python source code analyzer which looks for programming errors, helps enforcing a coding standard and sniffs for some code smells (as defined in Martin Fowler's Refactoring book).

Installation steps

  1. In the Settings/Preferences dialog (CTRL+Alt+S), click Plugins. The Plugins page opens.
  2. Click Browse repositories.
  3. In the Browse Repositories dialog that opens, right-click on the plugin named Pylint and select Download and Install.
  4. Confirm your intention to download and install the selected plugin.
  5. Click Close.
  6. Click OK in the Settings dialog and restart PyCharm for the changes to take effect.

Configuration

The only configuration needed is to set the path to Pylint executable, and only if is not already inside the PATH environment variable.

To reach the Plugin configuration screen you can open Settings/Preferences dialog (CTRL+Alt+S), click Other Settings and then Pylint or simply click the gear icon from the side bar of the Pylint tool window.

To change the path to your Pylint executable you can either type the path directly or use the Browse button to open a file selection dialog.

Once you changed the path you should press the Test button to check if the plugin is able to run the executable.

FAQ

How can I prevent the code inspection to run on a specific folder?

The easiest way to ignore a specific folder is to mark it as Excluded from PyCharm/IDEA:

  1. Open PyCharm/IDEA Settings -> your project -> Project structure
  2. Select the directory you want to exclude
  3. Click the Excluded button (red folder icon)
