yapf是一款由Google开源的Python代码自动格式化工具,它根据PEP 8规范可以帮我们自动格式化我们的代码,让代码更规范、更漂亮。
本文介绍VSCODE下面安装配置yapf
pip install yapf
yapf -i filename.py //这样可以成功格式化
启用
其中最大列宽被限制为80,如果超过80,在格式化时就会被yapf换行,随着现在人们的显示器越来越大,分辨率也越来越高,我们可以将这个限制适当修改。
找到对应项目里面的文件
../site-packages/yapf/yapflib/style.py
找到下面的函数

修改为COLUMN_LIMIT=120,
这样你的列宽就修改为120了。
vscode的settings.json做如下修改,输入想要的字符数:
{
"python.formatting.provider": "yapf",
"python.formatting.yapfArgs": ["--style", "{column_limit: 79}"],
}
