The Uncompromising Code Formatter

By using Black, you agree to cede control over minutiae of hand-formatting. In return,

Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting.

You will save time and mental energy for more important matters.

PyCharm/IntelliJ IDEA增加
1、Install black.
$ pip install black
Locate your black installation folder.
On macOS / Linux / BSD:

$ which black
/usr/local/bin/black # possible location
On Windows:

$ where black
%LocalAppData%\Programs\Python\Python36-32\Scripts\black.exe # possible location
2、Open External tools in PyCharm/IntelliJ IDEA
On macOS:

PyCharm -> Preferences -> Tools -> External Tools

On Windows / Linux / BSD:

File -> Settings -> Tools -> External Tools

Click the + icon to add a new external tool with the following values:

Name: Black
Description: Black is the uncompromising Python code formatter.
Program: <install_location_from_step_2>
Arguments: "$FilePath$"
Format the currently opened file by selecting Tools -> External Tools -> black.

3、Alternatively, you can set a keyboard shortcut by navigating to Preferences or Settings -> Keymap -> External Tools -> External Tools - Black.
Optionally, run Black on every file save:

Make sure you have the File Watcher plugin installed.
Go to Preferences or Settings -> Tools -> File Watchers and click + to add a new watcher:
Name: Black
File type: Python

Program: <install_location_from_step_2>

Uncheck "Auto-save edited files to trigger the watcher"
