python click库_python中click用法?

import click

@click.command()
@click.option('--count', default=1, help='Number of greetings.')
@click.option('--name', prompt='Your name',
              help='The person to greet.')
def hello(count, name):
    """Simple program that greets NAME for a total of COUNT times."""
    for x in range(count):
        click.echo('Hello %s!' % name)

if __name__ == '__main__':
    hello()

运行输出如下，help用于参数说明，default用于设置默认值

$ python hello.py --count=3
Your name: John
Hello John!
Hello John!
Hello John!
