VS Code python

Extensions

• Python (wich should install Pylance for static type checking)
• Ruff, one tool for linting, black formatting, isort etc
• Jupyter (Keymap, Slide show, cell tags)
• Coverage gutters for code coverage
• Remote ssh/explorer to connect to distant servers easily (no need for jupyther hub now)
• GitLens to supercharge git
• Vim
• Material icon theme
• Theme (publisher:"Mhammed Talhaouy"), personnal preference

Configuration file

Here is my config file, useful to handle copy paster in vim, or autolaunch ruff on save for example:

{
    "editor.minimap.enabled": false,  
    // Bracket-pair colorization  
    "editor.bracketPairColorization.enabled": false,  
    "notebook.diff.ignoreMetadata": true,  
    "gitlens.hovers.currentLine.over": "line",  
    "workbench.iconTheme": "material-icon-theme",  
    "files.autoSave": "afterDelay",  
    "git.confirmSync": false,  
    "jupyter.notebookFileRoot": "${workspaceFolder}",  
    "vim.commandLineModeKeyBindingsNonRecursive": [],  
    "vim.useSystemClipboard": true,  
    "vim.handleKeys": {  
        "<C-c>": false,  
        "<C-v>": false  
    },  
    "vim.visualModeKeyBindingsNonRecursive": [  
    {  
        "before": [  
            "p",  
        ],  
        "after": [  
            "p",  
            "g",  
            "v",  
            "y"  
        ]  
    }  
    ],  
    "[python]": {  
        "editor.formatOnSave": true,  
        "editor.codeActionsOnSave": {  
        "source.organizeImports": true,  
        "source.fixAll": true  
        },  
        "editor.formatOnType": true,
        "editor.defaultFormatter": "charliermarsh.ruff"
    },  
    "python.analysis.typeCheckingMode": "basic",  
    "python.analysis.autoImportCompletions": true,  
    "python.analysis.stubPath": "",  
    "python.analysis.indexing": true,

    },  
    "python.analysis.inlayHints.pytestParameters": true,  
    "pythonTestExplorer.testFramework": "pytest",  
    "python.analysis.inlayHints.functionReturnTypes": false,  
}  

Testing

poetry add pytest pytest-cov

The first one will give a coverage visible directly in vs code, the other one a report inside the terminal bash pytest . --cov-report xml:cov.xml --cov . pytest . --cov-report term --cov .

Profiling

poetry add py-spy

You can then launch the py-spy to sample the running process and get a nice svg visualization:
bash py-spy record --pid 1400174 --format speedscope -r 1000
