Step 5: Install packages in your Python environment

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.

View environments

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 environments 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 more information about working with environments, see How to create and manage Python environments in Visual Studio environments.

Note

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

With a Python project open, you can open the Python Environments window from Solution Explorer. Right-click Python Environments and select View All Python Environments.
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. You can also use the project you previously created and replace the code.

from math import radians import numpy as np # installed with matplotlib import matplotlib.pyplot as plt def main(): x = np.arange(0, radians(1800), radians(12)) plt.plot(x, np.cos(x), 'b') plt.show() main()
In the editor window, hover over the

numpy
and
matplotlib
import statements. You’ll notice that they aren’t resolved. To resolve the import statements, install the packages to the default global environment.
When you look at the editor window, notice that when you hover over the

numpy
and
matplotlib
import statements that they aren’t resolved. The reason is the packages haven’t been installed to the default global environment.

For example, select Open interactive window and an Interactive window for that specific environment appears in Visual Studio.
Use the drop-down list below the list of environments to switch to the Packages tab.The Packages tab lists all packages that are currently installed in the environment.

Install packages using the Python Environments window

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

matplotlib
by entering its name into the search field and then selecting the Run command: pip install matplotlib option. Running the command will install
matplotlib
, and any packages it depends on (in this case that includes
numpy
).
Choose the Packages tab.
Consent to elevation if prompted to do so.
After the package is installed, it appears in the Python Environments window. The X to the right of the package uninstalls it.
Consent to elevation if prompted to do so.
After the package installs, 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.

Review elements in Solution Explorer

Take some time to familiarize yourself with Solution Explorer, where you can browse files and folders in your project.

(1) At the top level is the solution, which by default has the same name as your project. A solution, which is shown as an .sln file on disk, is a container for one or more related projects. For example, if you write a C++ extension for your Python application, that C++ project can be in the same solution. The solution might also contain a project for a web service, and projects for dedicated test programs.
(2) Your project is highlighted in bold and uses the name you entered in the Create a new project dialog. On disk, this project is represented by a .pyproj file in your project folder.
(3) Under your project you see source files. In this example, you have only a single .py file. Selecting a file displays its properties in the Properties window. If you don’t see the Properties window, select the wrench icon in the Solution Explorer banner. Double-clicking a file opens it in whatever way is appropriate for that file.
(4) Also under the project is the Python Environments node. Expand the node to show the available Python interpreters.
(5) Expand an interpreter node to see the libraries installed in that environment.

Right-click any node or item in Solution Explorer to show a context menu of applicable commands. For example, Rename lets you change the name of a node or item, including the project and the solution.

Tutorial: Work with Python in Visual Studio

In this tutorial, you learn how to work with Python in Visual Studio. Python is a popular programming language that’s reliable, flexible, easy to learn, and free to use on all operating systems. Python is supported by a strong developer community and many free libraries. The language supports all kinds of development, including web applications, web services, desktop apps, scripting, and scientific computing. Many universities, scientists, casual developers, and professional developers use Python. Visual Studio provides first-class language support for Python.

This tutorial guides you through a six-step process:

Step 1: Create a Python project (this article)
Step 2: Write and run code to see Visual Studio IntelliSense at work
Step 3: Create more code in the Interactive REPL window
Step 4: Run the completed program in the Visual Studio debugger
Step 5: Install packages and manage Python environments
Step 6: Work with Git

This article covers the tasks in Step 1. You create a new project and review the UI elements visible in Solution Explorer.

Review Python interpreters

The following table lists Python interpreters that can be used with Visual Studio.

Interpreter	Description	Notes
CPython	The “native” and most commonly used interpreter, available in 32-bit and 64-bit versions (32-bit recommended). Includes the latest language features, maximum Python package compatibility, full debugging support, and interop with IPython. Review the considerations in Should I use Python 2 or Python 3? to help determine which version of Python to install.	Visual Studio 2015 and earlier don’t support Python 3.6 or later, and can return errors like Unsupported python version 3.6. For Visual Studio 2015 and earlier, use Python 3.5 or earlier.
IronPython	A .NET implementation of Python, available in 32-bit and 64-bit versions. Provides C#/F#/Visual Basic interop, access to .NET APIs, standard Python debugging (but not C++ mixed-mode debugging), and mixed IronPython/C# debugging.	IronPython doesn’t support virtual environments.
Anaconda	An open data science platform powered by Python. Includes the latest version of CPython and most of the difficult-to-install packages.	If you’re unable to decide on an interpreter, we recommend using Anaconda.
PyPy	A high-performance tracing JIT implementation of Python. Good for long-running programs and situations where you identify performance issues but can’t find other resolutions.	Works with Visual Studio but with limited support for advanced debugging features.
Jython	An implementation of Python on the Java Virtual Machine (JVM). Similar to IronPython, code running in Jython can interact with Java classes and libraries. However, many of the libraries intended for CPython might not be accessible.	Works with Visual Studio but with limited support for advanced debugging features.

Step 1: Create a new Python project

A project is how Visual Studio manages all the files that come together to produce a single application. Application files include source code, resources, and configurations. A project formalizes and maintains the relationships among all the project’s files. The project also manages external resources that are shared between multiple projects. A project allows your application to effortlessly expand and grow. Using projects is easier than managing relationships by hand in unplanned folders, scripts, text files, and your memory.

This tutorial begins with a simple project containing a single, empty code file.

In Visual Studio, select File > New > Project to open the New Project dialog. You can also use the keyboard shortcut Ctrl+Shift+N. In the dialog, you can browse templates across different languages, select a template for your project, and specify where Visual Studio places files.
To view Python templates, select Installed > Python on the left menu, or search for “Python.” The search option is a great way to find a template when you can’t remember its location in the languages tree.

Python support in Visual Studio includes several project templates, including web applications using the Bottle, Flask, and Django frameworks. For the purposes of this walkthrough, however, let’s start with an empty project.
Select the Python Application template, specify a name for the project, and select OK.

In Visual Studio, select File > New > Project or use the keyboard shortcut Ctrl+Shift+N. The Create a new project screen opens, where you can search and browse templates across different languages.
To view Python templates, search for python. Search is a great way to find a template when you can’t remember its location in the languages tree.

Python web support in Visual Studio includes several project templates, such as web applications in the Bottle, Flask, and Django frameworks. When you install Python with the Visual Studio Installer, select Python Web Support under Optional to install these templates. For this tutorial, start with an empty project.
Select the Python Application template, and select Next.
On the Configure your new project screen, specify a name and file location for the project, and then select Create.

After a few moments, your new project opens in Visual Studio:

Here’s what you see:

(1) The Visual Studio Solution Explorer window shows the project structure.
(2) The default code file opens in the editor.
(3) The Properties window shows more information for the item selected in Solution Explorer, including its exact location on disk.

Version Control integration

Collaborate on code with Git

Use Git as the default source control experience in Visual Studio right out of the box. From the new Git menu, you can create or clone repositories from GitHub or Azure DevOps. Use the integrated Git tool windows to commit and push changes to your code, manage branches, sync with your remote repositories, and resolve merge conflicts.

Detect your environment

Visual Studio shows all known environments in the Python Environments window. It automatically detects updates to existing interpreters.

If Visual Studio doesn’t detect an installed environment, see Manually identify an existing environment.

If you want to provide new forms of detection for Python environments, see PTVS Environment Detection (github.com).

Registry entries

Visual Studio (all versions) automatically detects each installed Python interpreter and its environment by checking the registry according to PEP 514 – Python registration in the Windows registry. Python installations are typically found under the HKEY_LOCAL_MACHINE\SOFTWARE\Python (32-bit) and HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Python (64-bit) key within nodes for the distribution, such as PythonCore (CPython) and ContinuumAnalytics (Anaconda).

Develop Python applications

Move an interpreter

If you move an existing interpreter to a new location by using the file system, Visual Studio doesn’t automatically detect the change.

If you originally specified the location of the interpreter through the Python Environments window, you can edit its environment by using the Configure tab in that window to identify the new location. For more information, see Manually identify an existing environment.
If you installed the interpreter by using an installer program, use the following steps to reinstall the interpreter in the new location:
1. Restore the Python interpreter to its original location.
2. Uninstall the interpreter by using its installer, which clears the registry entries.
3. Reinstall the interpreter at the new location.
4. Restart Visual Studio, which should autodetect the new location in place of the old location.

This process ensures that the registry entries that identify the interpreter’s location, which Visual Studio uses, are properly updated. Using an installer also handles any other side effects that might exist.

Visual Studio 2015 and earlier

Prior to Visual Studio 2017, Python support was released as a standalone extension. We are no longer actively developing these versions, but if you are unable to upgrade to Visual Studio 2017 yet, you can use these older installers to get Python support.

PTVS 2.2.6 is the latest available version for Visual Studio 2015. You can also find it in the Visual Studio 2015 installer by selecting “Custom” and looking under the “Programming Languages” category.

PTVS 2.2.2 is the last release for Visual Studio 2013 users.

Thank you for using and supporting Python Tools for Visual Studio.

Install Python interpreters

There are several options for installing Python interpreters to work with Visual Studio. You can install an interpreter when you install the Python workload, or you can install an interpreter after a workload is present. Interpreters can also be installed manually outside of the Visual Studio Installer.

When you install the Python development workload in Visual Studio 2017 and later, Python 3 (64-bit) also installs by default. As an option, you can choose to install the 32-bit or 64-bit version of Python 2 or Python 3, along with Miniconda (Visual Studio 2019) or Anaconda 2/Anaconda 3 (Visual Studio 2017). The steps for this type of installation are described in Install Python support in Visual Studio.

An alternate approach is to install standard Python interpreters by using the Add Environment feature in Visual Studio. This option is available in the Python Environments window and the Python toolbar.

Python interpreters can also be installed manually outside of the Visual Studio Installer. Suppose you install Anaconda 3 before you install Visual Studio. You don’t need to reinstall Anaconda through the Visual Studio Installer. You can also install a newer version of an interpreter if it isn’t yet listed in the Visual Studio Installer.

Download and install the Python workload

Complete the following steps to download and install the Python workload.

Download and run the latest Visual Studio Installer for Windows. Python support is present in release 15.2 and later. If you have Visual Studio installed already, open Visual Studio and run the installer by selecting Tools > Get Tools and Features.

Tip

The Community edition is for individual developers, classroom learning, academic research, and open source development. For other uses, install Visual Studio Professional or Visual Studio Enterprise.
The installer provides a list of workloads that are groups of related options for specific development areas. For Python, select the Python development workload and select Install:
Python installation options Description Python distributions Choose any combination of Python distribution that you plan to work with. Common options include 32-bit and 64-bit variants of Python 2, Python 3, Miniconda, Anaconda 2, and Anaconda 3. Each option includes the distribution’s interpreter, runtime, and libraries. Anaconda, specifically, is an open data science platform that includes a wide range of preinstalled packages. Visual Studio automatically detects existing Python installations. For more information, see The Python Environments window. Also, if a newer version of Python is available than the version shown in the installer, you can install the new version separately and Visual Studio detects it. Cookiecutter template support Install the Cookiecutter graphical UI to discover templates, input template options, and create projects and files. For more information, see Use the Cookiecutter extension. Python web support Install tools for web development including HTML, CSS, and JavaScript editing support, along with templates for projects using the Bottle, Flask, and Django frameworks. For more information, see Python web project templates. Python native development tools Install the C++ compiler and other necessary components to develop native extensions for Python. For more information, see Create a C++ extension for Python. Also install the Desktop development with C++ workload for full C++ support.
By default, the Python workload installs for all users on a computer under:

How to run Python in Visual Studio Code on Windows 10/11 [ 2024 Update ] Python Developers

Prerequisites

Visual Studio supports Python version 3.7. While it’s possible to use an earlier version of Visual Studio to edit code written in earlier versions of Python, those versions of Python aren’t officially supported. Visual Studio features such as IntelliSense and debugging might not work with earlier versions of Python.
For Visual Studio 2015 and earlier, use Python 3.5 or earlier. You must manually install one of the Python interpreters.

Anaconda distributions

Although Visual Studio offers to install the Anaconda distribution, your use of the distribution and other packages from Anaconda Repository are bound by the Anaconda Terms of Service. These terms might require some organizations to pay Anaconda for a commercial license, or else configure the tools to access an alternate repository. For more information, see the Conda channels documentation.

Test your install

Quickly check your installation of Python support:

Launch Visual Studio.
Select Alt + I to open the Python Interactive window.
In the window, enter the statement

2+2
.

The statement output

displays in the window. If you don’t see the correct output, recheck your steps.
