Python in Visual Studio Code Install Python and the Python extension #. The tutorial guides you through installing Python and using the extension. Insiders program #. The Insiders program allows you to try out and automatically install new versions of the Python. Run Python code #. For Python, select the Python development workload and select Install: To quickly test Python support, launch Visual Studio, press Alt + I to open the Python Interactive window, and enter 2+2. If you don't see the output of 4, recheck your steps.

1. Visual Code Studio Python Debug
2. Using Python In Visual Studio

Previous step: Run code in the debugger

The Python developer community has produced thousands of useful packages that you can incorporate into your own projects. Visual Studio provides a UI to manage packages in your Python environments.

Visual Code Studio Python Debug

View environments

1. Select the View > Other Windows > Python Environments menu command. The Python Environments window opens as a peer to Solution Explorer and shows the different environments available to you. The list shows both environments that you installed using the Visual Studio installer and those you installed separately. That includes global, virtual, and conda environments. The environment in bold is the default environment that's used for new projects. For additional information about working with environments, see How to create and manage Python environments in Visual Studio environments.

   Note

   You can also open the Python Environments window by selecting the Solution Explorer window and using the Ctrl+K, Ctrl+` keyboard shortcut. If the shortcut doesn't work and you can't find the Python Environments window in the menu, it's possible you haven't installed the Python workload. See How to install Python support in Visual Studio for guidance about how to install Python.

2. The environment's Overview tab provides quick access to an Interactive window for that environment along with the environment's installation folder and interpreters. For example, select Open interactive window and an Interactive window for that specific environment appears in Visual Studio.

3. Now, create a new project with File > New > Project, selecting the Python Application template. In the code file that appears, paste the following code, which creates a cosine wave like the previous tutorial steps, only this time plotted graphically. Alternatively, you can use the project you previously created and replace the code.

4. With a Python project open, you can also open the Python Environments window from Solution Explorer by right-clicking Python Environments and selecting View All Python Environments

5. Looking at the editor window, you'll notice that if you hover over the numpy and matplotlib import statements that they are not resolved. That's because the packages have not been installed to the default global environment.

Install packages using the Python Environments window

1. From the Python Environments window, select the default environment for new Python projects and choose the Packages tab. You will then see a list of packages that are currently installed in the environment.

2. Install matplotlib by entering its name into the search field and then selecting the Run command: pip install matplotlib option. This will install matplotlib, as well as any packages it depends on (in this case that includes numpy).

3. Consent to elevation if prompted to do so.

4. After the package is installed, it appears in the Python Environments window. The X to the right of the package uninstalls it.

   Note

   A small progress bar might appear underneath the environment to indicate that Visual Studio is building its IntelliSense database for the newly-installed package. The IntelliSense tab also shows more detailed information. Be aware that until that database is complete, IntelliSense features like auto-completion and syntax checking won't be active in the editor for that package.

   Visual Studio 2017 version 15.6 and later uses a different and faster method for working with IntelliSense, and displays a message to that effect on the IntelliSense tab.

Run the program

Using Python In Visual Studio

1. Now that matplotlib is installed, run the program with (F5) or without the debugger (Ctrl+F5) to see the output:
