在vscode中使用yapf，并手动修改yapf的配置

下面的方法同时适用于Linux和Windows平台

参考：GitHub - google/yapf: A formatter for Python files

安装yapf

pip install yapf

手动导出yapf的配置文件，命令行中运行

yapf --style-help > yapf_style.cfg

手动修改yapf的配置，修改自己想修改的配置项

vim yapf_style.cfg

将yapf_style.cfg放在工程目录下，或者与要格式化的文件在同一目录

如果想一劳永逸的话，可以将yapf_style.cfg改名为style，直接放入$HOME/.config/yapf/下，其中HOME目录在windows上需要自己设置添加进PATH，Linux和Mac os就是~，这时vscode配置里yapfArgs可以不写入。

YAPF Github上的说明:

YAPF will search for the formatting style in the following manner:

1. Specified on the command line
2. In the [style] section of a .style.yapf file in either the current directory or one of its parent directories.
3. In the [yapf] section of a setup.cfg file in either the current directory or one of its parent directories.
4. In the ~/.config/yapf/style file in your home directory.

If none of those files are found, the default style is used (PEP8).

详细可以参考YAPF的Github主页

在vscode中使用yapf，并加载自己修改后的配置文件yapf_style.cfg

    "python.formatting.provider": "yapf",
    "python.formatting.yapfArgs": [
        "--sytle={based_on_style: yapf, indent_width: 4, column_limit: 120}"
    ],

另外给出autopep8的一些配置：

    "python.formatting.autopep8Args": [
        "--max-line-length=120",
    ],

flake8的配置

    "python.linting.flake8Enabled": true,
    "python.linting.lintOnSave": true,
    "python.linting.flake8Args": [
        "--max-line-length=120",
        "--ignore=E501, E262",
    ],

black的配置

    "python.linting.blackArgs": [
        "--line-length", "120",
        "--skip-string-normalization",
    ],
