1 day ago Let me just say, the way I would run this in a normal terminal. I'd use a command like python3. No longer able to execute python code in Vscode. VSCode 1.29.1 Code Runner 0.9.5. When running a Python script using Code Runner the virtualenv is not activated before the code is run in the terminal for the first time, causing my code fail. The virtualenv is activated after the script fails and I can then run my code successfully until I close the terminal window. Hi I recently got a new macbook air for school and have downloaded vsc and python 3.9.7, with code runner, Pylance and Python. My task is to create a program that takes a bunch of grades and calculates the percentages and inputs them into a table, but i'm having trouble with the input function on mac. You define Jupyter-like code cells within Python code using a #%% comment: #%% msg = 'Hello World' print (msg) #%% msg = 'Hello again' print (msg) Note: Make sure to save the code shown above in a file with a.py extension. When the Python extension detects a code cell, it adds Run Cell and Debug Cell CodeLens adornments. Python tests are Python classes that reside in separate files from the code being tested. Each test framework specifies the structure and naming of tests and test files. Once you write tests and enable a test framework, VS Code locates those tests and provides you with various commands to run and debug them.
Python is fully supported in Visual Studio Code through extensions. Popular extensions in the Marketplace provide code completion, linting, debugging, code formatting, snippets, and more.
Download VS Code - If you haven't downloaded VS Code yet, quickly install for your platform (Windows, Mac, Linux).
Install Python Extension
VS Code is a fast editor and ships with only the basic features. Add Python language support to VS Code by installing one of the popular Python extensions.
- Select an extension.
- Install the extension by typing
ext install
into the Command Palettekb(workbench.action.showCommands)
.
Tip: The extensions shown above are dynamically queried. Click on an extension tile above to read the description and reviews to decide which extension is best for you. See more in the Marketplace.
The examples in this document will use Don Jayamanne's popular and full featured Python Extension.
Vscode Code Runner Python3
Code Completion
Python extensions support code completion and Intellisense. Intellisense is a general term for a number of features, including intelligent code completion (in-context method and variable suggestions) across all your files and for built-in and thirty-party modules.

Quickly see methods, class members, and documentation.
Tip: Trigger code completion with kb(editor.action.triggerSuggest)
.
Linting
Linting is the analysis of your Python code for potential errors. Use Visual Studio Code to quickly navigate to the errors and warnings in your code.
Tip: Don Jayamanne's Python extension gives you the option of using three different linters - Pylint, Pep8, and Flake8. See the wiki for more details.
Debugging
No more print
statement debugging! Set breakpoints, inspect data, and use the debug console. Debug a number of different type of Python applications, including multi-threaded, web, and remote applications.
Tip: Follow the instructions in the wiki for getting started with debugging, including setting up your launch.json
debugging configuration and troubleshooting common issues.
Tip: Read more about general information about debugging in Visual Studio Code in the debugging document.
Snippets
Snippets will take productivity to the next level. You can configure your own snippets and use snippets provided by an extension.
Tip: Snippets appear in the same way as code completion kb(editor.action.triggerSuggest)
.
Configuration
You will need an extension and Python installed. Other dependencies are optional and depend on the features you want to use. Read through the requirements on the extension's README.
Next Steps
- Install an Extension - Python extension are available in the Marketplace.
- Basic Editing - Learn about the powerful VS Code editor.
- Code Navigation - Move quickly through your source code.
Common Questions
Q: Why won't linting work for me?
A: First make sure you have installed an extension. Next, many extensions have a dependency on an external package. Install the required packages using a Python package manager like pip or easy_install. You can read more about troubleshooting linting issues here.
