The Python Language Server\u00a0<\/span><\/span>now has<\/span><\/span>\u00a0linting capabilities, and its latest\u00a0<\/span><\/span>release\u00a0<\/span><\/span>include<\/span><\/span>s\u00a0<\/span><\/span>new linting m<\/span><\/span>essages\u00a0<\/span><\/span>and\u00a0<\/span><\/span>a\u00a0<\/span><\/span>variety<\/span><\/span>\u00a0of<\/span><\/span>\u00a0additional<\/span><\/span>\u00a0general improvements<\/span><\/span>, which are listed in the section \u201cOther changes and enhancements\u201d below<\/span><\/span>.\u00a0<\/span><\/span>\u00a0<\/span><\/span>\u00a0<\/span> <\/span><\/p>\n

The linting messages provided by the Python Language Server include<\/span><\/span>\u00a0detecting<\/span><\/span>\u00a0unresolved imports<\/span><\/span>, undefined variable<\/span><\/span>s<\/span><\/span>, too many arguments in a function call<\/span><\/span>, unknown keyword argument<\/span><\/span>s<\/span><\/span>\u00a0and\u00a0<\/span><\/span>i<\/span><\/span>nheriting from something that is not a class<\/span><\/span>.<\/span><\/span>\u00a0To see the full\u00a0<\/span><\/span>detailed\u00a0<\/span><\/span>list\u00a0<\/span><\/span>of linting messages, you can check the\u00a0<\/span><\/span>documentation<\/span><\/span><\/a>\u00a0in the\u00a0<\/span><\/span>Language Server GitHub repo<\/span><\/span><\/a>\u00a0or the\u00a0<\/span><\/span>settings reference<\/span><\/span><\/a> page within the Python for Visual Studio Code docs.<\/span><\/span>\u00a0<\/span><\/p>\n

Improvements to\u00a0<\/span>Jupyter\u00a0Notebook cell debugging\u00a0<\/span>\u00a0<\/span><\/h2>\n

In the\u00a0<\/span><\/span>August release<\/span><\/span><\/a>, we added\u00a0<\/span><\/span>the ability to debug\u00a0<\/span><\/span>J<\/span><\/span>upyter<\/span>\u00a0notebook cells<\/span><\/span>\u00a0where you can step into user code.\u00a0<\/span><\/span>In this release,<\/span><\/span>\u00a0this feature is enhanced with the\u00a0<\/span><\/span>option to\u00a0<\/span><\/span>also\u00a0<\/span><\/span>step<\/span><\/span>\u00a0into non-user code<\/span><\/span>\u00a0if\u00a0<\/span><\/span>needed<\/span><\/span>.<\/span><\/span>\u00a0<\/span><\/span>T<\/span><\/span>o enable, open the settings page (<\/span><\/span>File > Preferences > Settings<\/span><\/span>)<\/span><\/span>, search for \u201cData Science: Debug Just My Code\u201d and\u00a0<\/span><\/span>uncheck the option<\/span><\/span>.<\/span><\/span>\u00a0<\/span><\/p>\n

Once the setting is disabled, you\u2019ll be able to step into function calls and, for example, inspect the non-user code behavior and how variables change when it\u2019s being executed.\u00a0<\/span><\/span>\u00a0<\/span><\/p>\n
