Though you can’t actually link up two processes together with a pipe by using the run() function, at least not without delegating it to the shell, you can simulate piping by judicious use of the stdout attribute. If you’re on a UNIX-based system where almost all typical shell commands...

实际上 Python 标准库提供了一个默认的命令行工具 Argparse,但是对于 Click 来说 Argparse 使用起来非常的繁琐和麻烦,大多数人都很少使用它。Argparse 对比与 Click 就像网页解析中使用的 re 和 BeautifulSoup。 Click 有三个非常重要的特性: 任意嵌套命令
