我想知道如何执行以下python代码？

Question

import argparse

import googleapiclient.discovery


def create_service():

return googleapiclient.discovery.build('storage', 'v1')


def list_buckets(service, project_id):
   buckets = service.buckets().list(project=project_id).execute()
   return buckets


def main(project_id):
  service = create_service()
  buckets = list_buckets(service, project_id)
  print(buckets)


if __name__ == '__main__':
 parser = argparse.ArgumentParser(
    description=__doc__,
    formatter_class=argparse.RawDescriptionHelpFormatter)
 parser.add_argument('project_id', help='Your project iD')

 args = parser.parse_args()
 main(args.project_id)

＃需要知道如何运行这个例子。因为我是python的新手。当我执行它时，给出了很少的参数。

Answer 1

我认为您看到的错误是：

usage: your_script.py [-h] project_id
your_script.py: error: too few arguments

您需要指定项目ID。因此，如果您之前正在运行python your_script.py，则需要改为运行python your_script.py your-project-id 。
