Python 命令行参数

import argparse
def test_for_sys(year, name, body):
    print('the year is', year)
    print('the name is', name)
    print('the body is', body)
parser = argparse.ArgumentParser(description='Test for argparse')
parser.add_argument('--name', '-n', help='name 属性，非必要参数')
parser.add_argument('--year', '-y', help='year 属性，非必要参数，但是有默认值', default=2017)
parser.add_argument('--body', '-b', help='body 属性，必要参数', required=True)
args = parser.parse_args()
if __name__ == '__main__':
    try:
        test_for_sys(args.year, args.name, args.body)
    except Exception as e:
        print(e)

执行时：

python test_cmd.py -n Leijun --body "are you ok?"
