Vscode lanuch.json

Intro

使用launch.json

能够方便的运行需要传很多参数的代码文件

如下：

import math
import argparse  # 1、导入argpase包


def parse_args():
    parse = argparse.ArgumentParser(description='Calculate cylinder volume')  # 2、创建参数对象
    parse.add_argument('--radius', default=2, type=int, help='Radius of Cylinder')  # 3、往参数对象添加参数
    parse.add_argument('--height', default=4, type=int, help='height of Cylinder')
    args = parse.parse_args()  # 4、解析参数对象获得解析对象
    return args


def cal_vol(radius, height):
    vol = math.pi * pow(radius, 2) * height
    return vol


if __name__ == '__main__':
    args = parse_args()
    print(cal_vol(args.radius, args.height))  # 5、使用解析对象.参数获取使用命令行参数

运行上述代码的命令是

test1.py --radius 2 --height 3

创建json

那如何写在json中呢

{
    // 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 Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "cwd": "/home/hu/Projects/test",
            "args": [
                "--radius",
                "2",
                "--height",
                "2",

            ]
        }
    ]
}

然后
