The editor includes various features to help you be productive when writing code. For more information about editing in Visual Studio Code, see Basic Editing and Code Navigation. In this overview, we will describe the specific editing features provided by the Python extension, including steps on how to customize these features via user and workspace settings. Autocomplete and IntelliSenseIntelliSense is a general term for code editing features that relate to code completion. Take a moment to look at the example below. When print is typed, notice how IntelliSense populates auto-completion options. The user is also given a list of options when they begin to type the variable named, greeting. Autocomplete and IntelliSense are provided for all files within the current working folder. They're also available for Python packages that are installed in standard locations. Customize IntelliSense behaviorTo customize the behavior of the analysis engine, see the Python extension code analysis settings and autocomplete settings. You can also customize the general behavior of autocomplete and IntelliSense, even to disable these VS Code features entirely. See Customizing IntelliSense.
Enable IntelliSense for custom package locationsTo enable IntelliSense for packages that are installed in other, non-standard locations, add those locations to the Windows:
macOS/Linux:
For more on IntelliSense generally, see IntelliSense. Troubleshooting IntelliSenseIf autocomplete and IntelliSense aren't working for a custom module, check the following causes:
NavigationWhile editing, you can right-click different identifiers to take advantage of several convenient commands
Quick FixesThe add imports Quick Fix allows you to quickly complete import statements. First, begin by typing a package name within the editor. You will notice a Code Action is available to automatically complete the line of source code (as long as you have the module installed within the environment). Hover over the text (marked with a squiggle) and then select the Code Action light bulb when it appears. You can then select from a list of potential imports. Note: The functionality in the below examples is provided by the Pylance language server. The add imports Code Action also recognizes some of the popular abbreviations for the following common Python packages: The import suggestions list is ordered with import statements for packages (or modules) at the top. It will also include statements for more modules and/or members (classes, objects, etc.) from specified packages. Run Selection/Line in Terminal (REPL)The Python: Run Selection/Line in Python Terminal command (Shift+Enter) is a simple way to take whatever code is selected, or the code on the current line if there is no selection, and run it in the Python Terminal. An identical Run Selection/Line in Python Terminal command is also available on the context menu for a selection in the editor. VS Code automatically removes indents based on the first non-empty line of the selection, shifting all other lines left when needed. Source code that runs in the terminal/REPL is cumulative until the current instance of the terminal is closed. The command opens the Python Terminal if necessary; you can also open the interactive REPL environment directly using the Python: Start REPL command. (Initial startup might take a few moments especially if the first statement you run is an On first use of the Python: Run Selection/Line in Python Terminal command, VS Code may send the text to the REPL before that environment is ready, in which case the selection or line isn't run. If you come across this behavior, try the command again when the REPL has finished loading. FormattingFormatting makes code easier to read by human beings. It applies specific rules and conventions for line spacing, indents, spacing around operators, and so on. You can view an example on the autopep8 page. Keep in mind, formatting doesn't affect the functionality of the code itself. Linting helps to prevent errors by analyzing code for common syntactical, stylistic, and functional errors and unconventional programming practices. Although there is a little overlap between formatting and linting, the two capabilities are complementary. The Python extension supports source code formatting using either autopep8 (the default), black, or yapf. General formatting settings
Formatter-specific settingsThe following settings apply to the individual formatters. The Python extension looks for the formatter in the selected interpreter. To use a formatter in another location, specify that location in the appropriate custom path setting. The
When using custom arguments, each top-level element of an argument string that's separated by space on the command line must be a separate item in the args list. For example:

RefactoringThe Python extension adds the following refactoring functionalities: Extract Variable, Extract Method, Rename Module, and Sort Imports. Extracts all similar occurrences of the selected text within the current scope, and replaces it with a new variable. You can invoke this command by selecting the line of code you wish to extract as a variable. Then select the light-bulb that is displayed next to it. Extracts all similar occurrences of the selected expression or block within the current scope, and replaces it with a method call. You can invoke this command by selecting the lines of code you wish to extract as a method. Then select the light-bulb that is displayed next to it. Rename ModuleAfter a Python file/module is renamed, Pylance can find all instances that may need to be updated and provide you with a preview of all the changes. To customize which references need to be updated, you can toggle the checkboxes at the line or from the file level in Refactor Preview. Once you've made your selections, you can select Apply Refactoring or Discard Refactoring. Sort ImportsSort Imports uses the isort package to consolidate specific imports from the same module into
