1、flake8 安装配置

安装

pip install flake8
pip install yapf
pip install black

配置vscode

打开settings.json文件

  "python.linting.flake8Enabled": true,
  "python.formatting.provider": "yapf",
  "python.linting.flake8Args": ["--max-line-length=248"], 
  "python.linting.pylintEnabled": false 

2、常用配置

launch.json

{
    // 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": [


        {   "python": "/home/jovyan/.conda/envs/torch1.7/bin/python",
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        }
    ]
}

setting.json

{
    "terminal.integrated.fontFamily": "monospace",
    "terminal.integrated.fontSize": 16,
    "python.envFile": "${workspaceFolder}/.vscode/.env",
    "git.ignoreLimitWarning": true,
    "flake8.args": [
        "--ignore=E501"
    ],
    "editor.formatOnSave": true,
    "[python]": {
        "editor.defaultFormatter": "ms-python.black-formatter",
        "editor.formatOnSave": true,
    },
}

.env

PYTHONPATH=./:${PYTHONPATH}

3、函数注释插件

Python Docstring Generator

4、vscode中python代码不能跳转

更换Python解释器，选择你安装包的解释器

5、argparse中参数转化字典

为了方便查看argparse 的Namespace 对象中的内容，使用下面方式将其先转成dict，然后print出来。

parser = argparse.ArgumentParser()
parser.add_argument(...)
args = parser.parse_args()
print(json.dumps(vars(args), indent=4))

6、vscode中args异常字符传参

launch.json传参

{
    "version": "0.2.0",
    "configurations": [
        {
            "python": "/home/jovyan/.conda/envs/paddle/bin/python",
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "args": [
                "--url",
                "https://obs.cn-north-4.myhuaweicloud.com:443/1.4%25%8D%8E%E6%B6%A6%E7%BD%AE%E5%9C%B0%E5%BB%89%E6%B4%81%E4%BB%8E%E4%B8%9A%E5%87%86%E5%88%99.pdf?AccessKeyId=9OGNBX7CRRPA&Expires=1686801&Signature=4Lhj%2BBGDj%2BVyaBYE%3D"
            ]
        }
    ]
}

以上配置文件传参--url时，由于参数值中存在&字符，会将参数值进行切分，最终输入为https://obs.cn-north-4.myhuaweicloud.com:443/1.4%25%8D%8E%E6%B6%A6%E7%BD%AE%E5%9C%B0%E5%BB%89%E6%B4%81%E4%BB%8E%E4%B8%9A%E5%87%86%E5%88%99.pdf?AccessKeyId=9OGNBX7CRRPA，解决方法将"console": "integratedTerminal"调整为"console": "internalConsole"，修改结果如下：

{
    "version": "0.2.0",
    "configurations": [
        {
            "python": "/home/jovyan/.conda/envs/paddle/bin/python",
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "internalConsole",
            "args": [
                "--url",
                "https://obs.cn-north-4.myhuaweicloud.com:443/1.4%25%8D%8E%E6%B6%A6%E7%BD%AE%E5%9C%B0%E5%BB%89%E6%B4%81%E4%BB%8E%E4%B8%9A%E5%87%86%E5%88%99.pdf?AccessKeyId=9OGNBX7CRRPA&Expires=1686801&Signature=4Lhj%2BBGDj%2BVyaBYE%3D"
            ]
        }
    ]
}

7、Debug源码

添加"justMyCode": false， 形式如下：

{
    // 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": false
        }
    ]
}
