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.terminal.activateEnvironment": false,  
	"workbench.colorTheme": "Theme",  
	"gitlens.views.branches.branches.layout": "list",  
	"explorer.confirmDragAndDrop": false,  
	"files.exclude": {  
	"**/__pycache__": true,  
	"**/.pytest_cache": 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

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:

py-spy record --pid 1400174 --format speedscope -r 1000
