We are pleased to announce that the <\/span>April\u00a0<\/span>20<\/span>20<\/span>\u00a0<\/span>release of the Python Extension for Visual Studio Code is now available. You can <\/span>download the Python extension <\/span><\/a>from the\u00a0Marketplace, or install it directly from the extension gallery in Visual Studio Code. If you already have the Python extension installed, you can also get the latest update by restarting Visual Studio Code. You can learn more about <\/span>Python support in Visual Studio Code <\/span><\/a>in the documentation.\u00a0<\/span>\u00a0<\/span><\/p>\n

Debugger support for Django<\/span>\u00a0<\/span>and Flask auto<\/span>–<\/span>reload\u00a0<\/span>\u00a0<\/span><\/h2>\n

In the\u00a0<\/span>March release<\/span>\u00a0of the Python extension<\/span><\/a>, we\u00a0<\/span>introdu<\/span>ced our new Python debugger,\u00a0<\/span>debugpy<\/span><\/a>.<\/span>\u00a0<\/span>We\u2019re happy to\u00a0<\/span>announce that it supports live reloading of web applications, such as Django and Flask<\/span>.\u00a0<\/span>Now when you make edits to your application, you don\u2019t need to restart the debugger to get them applied<\/span> anymore. T<\/span>he web server is autom<\/span>atically reloaded in th<\/span>e<\/span>\u00a0same debugging session once the changes are saved.\u00a0<\/span>\u00a0<\/span><\/p>\n

To try it out, open a web application and add a debug configuration<\/span>\u00a0(<\/span>by\u00a0<\/span>clicking on\u00a0<\/span>Run > Add Configuration…<\/span><\/b>, or by opening the Run view and clicking on\u00a0<\/span>create launch.json file<\/span><\/b>).\u00a0<\/span>\u00a0<\/span><\/p>\n

Then select the framework used in your web application<\/span>.<\/span>\u00a0In this example, we selected\u00a0<\/span>Django.<\/span>\u00a0<\/span><\/p>\n

\"Debugger<\/a><\/p>\n

This will create a\u00a0<\/span><\/span>launch.json<\/span><\/span>\u00a0<\/span><\/span>file<\/span><\/span><\/a>\u00a0<\/span><\/span>and add a<\/span><\/span>\u00a0<\/span><\/span>run\/<\/span><\/span>debug<\/span><\/span>\u00a0configuration\u00a0<\/span><\/span>to it.<\/span><\/span>\u00a0<\/span><\/span>To get live reloading working, simply remove the \u201c–no-reload” flag in the\u00a0<\/span><\/span>args<\/span>\u00a0<\/span><\/span>property:<\/span><\/span><\/p>\n

\"Django<\/a><\/span><\/p>\n

This configuration will now look like this:<\/span><\/span>\u00a0<\/span><\/p>\n

      {\r\n            \"name\": \"Python: Django\",\r\n            \"type\": \"python\",\r\n            \"request\": \"launch\",\r\n            \"program\": \"${workspaceFolder}\\\\manage.py\",\r\n            \"args\": [\r\n                \"runserver\",\r\n            ],\r\n            \"django\": true\r\n        },<\/pre>\n
\n
Now when you start debugging (<\/span><\/span>F5<\/span><\/span><\/strong>)<\/span><\/span>,\u00a0<\/span><\/span>make changes to the application<\/span><\/span>\u00a0and save<\/span><\/span>\u00a0them<\/span><\/span>, the server will automatically reload.<\/span><\/span><\/p>\n<\/div>\n

<\/div>\n

 <\/br><\/p>\n
Pro tip:<\/span><\/span><\/strong>\u00a0<\/span><\/span>To enable live reload for Flask applications, set “FLASK_DEBUG”: “1” in the\u00a0<\/span><\/span>launch.json<\/span>\u00a0<\/span><\/span>file, as it\u2019s set to \u201c0\u201d by default.<\/span><\/span>\u00a0<\/span>\u00a0\u00a0<\/span><\/span>\u00a0<\/span><\/div>\n
