问题

Python的argparser的功能非常强大,在复杂工程项目中应用十分广泛。vscode是当前最流行的IDE开发环境,那么如何在vscode中配置argparser呢?

方法

(1) 修改.vscode的launch.json文件

{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"justMyCode": true,


"args": [
"--name","Alice",
"--age", "18",
],
}
]
}

(2) argparser中编程

from argparse import ArgumentParser

parser = ArgumentParser(description='test argparser')

parser.add_argument('--name', type=str, default='name', help='please specify your name in cmd')
parser.add_argument('--age', type=int, default=18, help='please specify your age in cmd')

arg = parser.parse_args()

print(arg.name, arg.age)

(3) 输出结果

Alice 18
