  1. Install black. `$ pip install black`

On macOS / Linux / BSD: `$ which black /usr/local/bin/black # possible location On Windows: **$ where black %LocalAppData%\Programs\Python\Python36-32\Scripts\b*lack.exe # possible location* Note that if you are using a virtual environment detected by PyCharm, this is an unneeded step. In this case the path to black is $PyInterpreterDirectory$/black`.
