【VSCode】支持argparser/接受命令行参数_argparse vscode

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)
