如何在python中执行click命令后更改存储在变量中的值(库导入click)

import click

@click.command()
@click.option('--name', prompt='Your name', help='The person to greet.')
def greet(name):
    click.echo('Hello, {}'.format(name))

if __name__ == '__main__':
    greet()

import click

@click.command()
@click.option('--name', prompt='Your name', help='The person to greet.')
@click.pass_context
def greet(ctx, name):
    click.echo('Hello, {}'.format(name))
    ctx.obj['name'] = name  # 在上下文对象中存储name的值

@click.command()
@click.pass_context
def update(ctx):
    name = ctx.obj['name']  # 从上下文对象中获取name的值
    new_name = name.upper()
    click.echo('Updated name: {}'.format(new_name))

@click.group()
@click.pass_context
def cli(ctx):
    ctx.obj = {}  # 初始化上下文对象

cli.add_command(greet)
cli.add_command(update)

if __name__ == '__main__':
    cli(obj={})  # 执行命令组，并传递一个空的上下文对象
