python代碼規範化工具yapf

yapf

yapf是一個Python文件代碼格式化工具,經過 YAPF 優化後，代碼風格可統一，在每次代碼審查中，也就沒有必要爭論風格了。

用法

usage: yapf [-h] [-v] [-d | -i] [-r | -l START-END] [-e PATTERN]
            [--style STYLE] [--style-help] [--no-local-style] [--verify]
            [files [files ...]]

Formatter for Python code.

positional arguments:
  files

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show version number and exit
  -d, --diff            print the diff for the fixed source
  -i, --in-place        make changes to files in place
  -r, --recursive       run recursively over directories
  -l START-END, --lines START-END
                        range of lines to reformat, one-based
  -e PATTERN, --exclude PATTERN
                        patterns for files to exclude from formatting
  --style STYLE         specify formatting style: either a style name (for
                        example "pep8" or "google"), or the name of a file
                        with style settings. The default is pep8 unless a
                        .style.yapf or setup.cfg file located in one of the
                        parent directories of the source file (or current
                        directory for stdin)
  --style-help          show style settings and exit
  --no-local-style      don't search for local style definition
  --verify              try to verify reformatted code for syntax errors

舉例

1. 僅僅查看須要優化的地方

yapf -d hello.py

2. 直接格式化代碼

yapf -i hello.py
