Previously Enthought provided Canopy, but it reached end of life in Note that these packages may not include the latest versions of Python or other libraries, and are not maintained or supported by the core Python team. To run Python conveniently from a command prompt, you might consider changing some default environment variables in Windows. If you regularly use multiple versions of Python, consider using the Python Launcher for Windows.

Windows allows environment variables to be configured permanently at both the User level and the System level, or temporarily in a command prompt. To temporarily set environment variables, open Command Prompt and use the set command:. These changes will apply to any further commands executed in that console, and will be inherited by any applications started from the console. Including the variable name within percent signs will expand to the existing value, allowing you to add your new value at either the start or the end.

Modifying PATH by adding the directory containing python. In this dialog, you can add or modify User and System variables. To change System variables, you need non-restricted access to your machine i. Administrator rights. Windows will concatenate User variables after System variables, which may cause unexpected results when modifying PATH. The set command, for temporarily modifying environment variables.

The setx command, for permanently modifying environment variables. Besides using the automatically created start menu entry for the Python interpreter, you might want to start Python in the command prompt. The installer has an option to set that up for you. This allows you to type python to run the interpreter, and pip for the package installer. Thus, you can also execute your scripts with command line options, see Command line documentation.

You need to set your PATH environment variable to include the directory of your Python installation, delimited by a semicolon from other entries. An example variable could look like this assuming the first two entries already existed :. Python uses it for the default encoding of text files e. If you have any Python 3.

The filesystem encoding see PEP for details. The Python launcher for Windows is a utility which aids in locating and executing of different Python versions. It allows scripts or the command-line to indicate a preference for a specific Python version, and will locate and execute that version. It will prefer per-user installations over system-wide ones, and orders by language version rather than using the most recently installed version.

The launcher was originally specified in PEP System-wide installations of Python 3. The launcher is compatible with all available versions of Python, so it does not matter which version is installed. To check that the launcher is available, execute the following command in Command Prompt:. You should find that the latest version of Python you have installed is started – it can be exited as normal, and any additional command-line arguments specified will be sent directly to Python.

If you have multiple versions of Python installed e. Per-user installations of Python do not add the launcher to PATH unless the option was selected on installation. To run the global interpreter, either deactivate the virtual environment, or explicitly specify the global Python version.

You should notice the version number of your latest Python 2. Now try changing the first line to be:. Re-executing the command should now print the latest Python 3. As with the above command-line examples, you can specify a more explicit version qualifier. Assuming you have Python 3. This is for backward compatibility and for compatibility with Unix, where the command python typically refers to Python 2.

The launcher should have been associated with Python files i. This means that when you double-click on one of these files from Windows explorer the launcher will be used, and therefore you can use the same facilities described above to have the script specify the version which should be used.

The key benefit of this is that a single launcher can support multiple Python versions at the same time depending on the contents of the first line. If the first line of a script file starts with!

Linux and other Unix like operating systems have native support for such lines and they are commonly used on such systems to indicate how a script should be executed. This launcher allows the same facilities to be used with Python scripts on Windows and the examples above demonstrate their use.

The supported virtual commands are:. The default Python will be located and used. As many Python scripts written to work on Unix will already have this line, you should find these scripts can be used by the launcher without modification.

Any of the above virtual commands can be suffixed with an explicit version either just the major version, or the major and minor version. New in version 3. Furthermore it is possible to specify a major and architecture without minor i.

The shebang lines can also specify additional options to be passed to the Python interpreter. For example, if you have a shebang line:. Then Python will be started with the -v option. The same. In some cases, a version qualifier can be included in a command to dictate which version of Python will be used by the command.

For example, a shebang line of! If no such option is found, the launcher will enumerate the installed Python versions and use the latest minor release found for the major version, which is likely, although not guaranteed, to be the most recently installed version in that family.

On bit Windows with both bit and bit implementations of the same major. This will be true for both bit and bit implementations of the launcher – a bit launcher will prefer to execute a bit Python installation of the specified version if available.

This is so the behavior of the launcher can be predicted knowing only what versions are installed on the PC and without regard to the order in which they were installed i.

If no relevant options are set, the commands python and python2 will use the latest Python 2. The command python3. In addition to environment variables, the same settings can be configured in the. INI file used by the launcher. The contents of an environment variable will override things specified in the INI file. While this information manages to be simultaneously verbose and terse, it should allow you to see what versions of Python were located, why a particular version was chosen and the exact command-line used to execute the target Python.

Python usually stores its library and thereby your site-packages folder in the installation directory. To completely override sys. The file based on the DLL name overrides the one based on the executable, which allows paths to be restricted for any program loading the runtime if desired. When the file exists, all registry and environment variables are ignored, isolated mode is enabled, and site is not imported unless one line in the file specifies import site.

Blank paths and lines starting with are ignored. Each path may be absolute or relative to the location of the file. Import statements other than to site are not permitted, and arbitrary code cannot be specified. Note that. When no. Subkeys which have semicolon-delimited path strings as their default value will cause each path to be added to sys. If a Python home is found, the relevant sub-directories added to sys. Otherwise, the core Python path is constructed from the PythonPath stored in the registry.

If a pyvenv. When running python. When Python is hosted in another. For those who want to bundle Python into their application or distribution, the following advice will prevent conflicts with other installations:. Include a. This will ignore paths listed in the registry and environment variables, and also ignore site unless import site is listed.

If you are loading python3. If you cannot use the previous suggestions for example, you are a distribution that allows people to run python. These will ensure that the files in a system-wide installation will not take precedence over the copy of the standard library bundled with your application. Next, to initialize the debugger, press F5. Since this is your first time debugging this file, a configuration menu will open from the Command Palette allowing you to select the type of debug configuration you would like for the opened file.

These different configurations are fully explained in Debugging configurations ; for now, just select Python File , which is the configuration that runs the current file shown in the editor using the currently selected Python interpreter. You can also start the debugger by clicking on the down-arrow next to the run button on the editor, and selecting Debug Python File in Terminal. The debugger will stop at the first line of the file breakpoint.

The current line is indicated with a yellow arrow in the left margin. If you examine the Local variables window at this point, you will see now defined msg variable appears in the Local pane.

The Status Bar also changes color orange in many themes to indicate that you’re in debug mode. The Python Debug Console also appears automatically in the lower right panel to show the commands being run, along with the program output. To continue running the program, select the continue command on the debug toolbar F5.

The debugger runs the program to the end. Tip Debugging information can also be seen by hovering over code, such as variables. In the case of msg , hovering over the variable will display the string Hello world in a box above the variable. You can also work with variables in the Debug Console If you don’t see it, select Debug Console in the lower right area of VS Code, or select it from the Select the blue Continue button on the toolbar again or press F5 to run the program to completion.

For full details, see Debugging configurations , which includes notes on how to use a specific Python interpreter for debugging. Tip: Use Logpoints instead of print statements : Developers often litter source code with print statements to quickly inspect variables without necessarily stepping through each line of code in a debugger.

In VS Code, you can instead use Logpoints. A Logpoint is like a breakpoint except that it logs a message to the console and doesn’t stop the program. For more information, see Logpoints in the main VS Code debugging article. Let’s now run an example that’s a little more interesting. In Python, packages are how you obtain any number of useful code libraries, typically from PyPI. For this example, you use the matplotlib and numpy packages to create a graphical plot as is commonly done with data science.

Note that matplotlib cannot show graphs when running in the Windows Subsystem for Linux as it lacks the necessary UI support. Return to the Explorer view the top-most icon on the left side, which shows files , create a new file called standardplot.

Tip : If you enter the above code by hand, you may find that auto-completions change the names after the as keywords when you press Enter at the end of a line.

To avoid this, type a space, then Enter. Next, try running the file in the debugger using the “Python: Current file” configuration as described in the last section. Unless you’re using an Anaconda distribution or have previously installed the matplotlib package, you should see the message, “ModuleNotFoundError: No module named ‘matplotlib'”. Such a message indicates that the required package isn’t available in your system. This command opens a command prompt for your selected interpreter.

A best practice among Python developers is to avoid installing packages into a global interpreter environment. You instead use a project-specific virtual environment that contains a copy of a global interpreter.

Once you activate that environment, any packages you then install are isolated from other environments. Such isolation reduces many complications that can arise from conflicting package versions. To create a virtual environment and install the required packages, enter the following commands as appropriate for your operating system:.

Note : For additional information about virtual environments, see Environments.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. By default, installing the Python development workload in Visual Studio and later also installs Python 3 bit. Alternately, you can install standard python interpreters from the Add Environment dialog. Select the Add Environment command in the Python Environments window or the Python toolbar, select the Python installation tab, indicate which interpreters to install, and select Install.

You can also manually install any of the interpreters listed in the table below outside of the Visual Studio installer. For example, if you installed Anaconda 3 before installing Visual Studio, you don’t need to install it again through the Visual Studio installer. You can also install an interpreter manually if, for example, a newer version of available that doesn’t yet appear in the Visual Studio installer.

Visual Studio supports Python version 3. While it is possible to use Visual Studio to edit code written in other versions of Python, those versions are not officially supported and features such as IntelliSense and debugging might not work.

For Visual Studio and earlier , you must manually install one of the interpreters. Although Visual Studio offers to install the Anaconda distribution, your use of the distribution and additional packages from Anaconda Repository are bound by the Anaconda Terms of Service. These terms may require some organizations to pay Anaconda for a commercial license, or else configure the tools to access an alternate repository.

See the Conda channels documentation for more information. Visual Studio all versions automatically detects each installed Python interpreter and its environment by checking the registry according to PEP – Python registration in the Windows registry. If Visual Studio does not detect an installed environment, see Manually identify an existing environment. Visual Studio shows all known environments in the Python Environments window, and automatically detects updates to existing interpreters.

If you move an existing interpreter to a new location 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, then edit its environment using the Configure tab in that window to identify the new location.

See Manually identify an existing environment. If you installed the interpreter using an installer program, then use the following steps to reinstall the interpreter in the new location:.

Following 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 may exist. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Table of contents Exit focus mode. Table of contents.

Includes the latest language features, maximum Python package compatibility, full debugging support, and interop with IPython. See also: Should I use Python 2 or Python 3?

Visual Studio and earlier don’t support Python 3. Use Python 3. IronPython, however, doesn’t support virtual environments.

An open data science platform powered by Python, and includes the latest version of CPython and most of the difficult-to-install packages. If you’re unable to decide, we recommend using Anaconda.

A high-performance tracing JIT implementation of Python that’s good for long-running programs and situations where you identify performance issues but cannot find other resolutions. Works with Visual Studio but with limited support for advanced debugging features. Similar to IronPython, code running in Jython can interact with Java classes and libraries.

However, many of the libraries intended for CPython may not be accessible.
