Click 不仅将一个普通的函数转化为一个命令行工具,还为它提供了选项、参数等,并且自动生成了帮助信息。 Click 支持选项和参数两种类型的脚本参数,使用 option 装饰器来使相应的函数增加命令行选项,使用 argument 装饰器使相应的函数增加命令参数。在以上示例中 count 是选项,而 name 是参数。从运行结果上来看选项会...
"" click.echo(f'Hello, {name}!') if __name__ == '__main__': hello() 在上面的例子中,@click.command()装饰器定义了一个命令,@click.option()则定义了一个可选参数--name,如果用户没有提供该参数,会通过prompt属性提示用户输入。 3.2.2 自定义类型转换与验证 Click允许开发者自定义参数类型,并...

@click.command()@click.argument('src',envvar='SRC',type=click.File('r'))defecho(src):click.echo(src.read()) And from the command line: $ export SRC=hello.txt $ echo Hello World! In that case, it can also be a list of different environment variables where the first one is picked...
另外,click也提供类似的显示进度条的工具(click.progress_bar),但我觉得它的外观不太容易懂,而且要写的代码也多一些。 我希望这篇文章能让你在改进开发者的体验上多花点时间。 原文:https://blog.sicara.com/perfect-python-command-line-interfaces-7d5d4efad6a2 ...
