To use this configuration layer, add `SPLayer 'lang#python'` to your custom configuration file.
### Syntax Checking
`checker` layer provide syntax checking feature, and for python it uses `flake8` package:
```sh
pip install --user flake8
```
### Buffer formatting
The default key binding for formatting buffer is `SPC b f`, and you need to install `yapf`. To enable automatic buffer formatting on save, load this layer with setting `format-on-save` to `1`.
```sh
pip install --user yapf
```
### Format imports
To be able to suppress unused imports easily, install [autoflake](https://github.com/myint/autoflake):
```sh
pip install --user autoflake
```
To be able to sort your imports, install [isort](https://github.com/timothycrosley/isort)
```sh
pip install --user isort
```
## Key bindings
### Inferior REPL process
Start a Python or iPython inferior REPL process with `SPC l s i`. If ipython is available in system executable search paths, ipython will be used to launch python shell; otherwise, default python interpreter will be used. You may change your system executable search path by activating a virtual environment.
Send code to inferior process commands:
| Key Binding | Description |
