How to add Python to PATH variable in Windows - Your Answer

 

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. The Microsoft Store installation of Python includes pip , the standard package manager.

Pip allows you to install and manage additional packages that are not part of the Python standard library. To confirm that you also have pip available to install and manage packages, enter pip --version. VS Code also contains a built-in terminal that enables you to open a Python command line with Windows Command prompt, PowerShell, or whatever you prefer, establishing a seamless workflow between your code editor and command line.

Once VS Code has been installed, you must also install the Python extension. Python is an interpreted language, and in order to run Python code, you must tell VS Code which interpreter to use.

We recommend using the most recent version of Python unless you have a specific reason for choosing something different. You can also use the Select Python Environment option on the bottom Status Bar if available it may already show a selected interpreter. The command presents a list of available interpreters that VS Code can find automatically, including virtual environments.

If you don't see the desired interpreter, see Configuring Python environments. The default terminal is PowerShell. Try the Python interpreter out by entering: print "Hello World". Python will return your statement "Hello World".

If you plan to collaborate with others on your Python code, or host your project on an open-source site like GitHub , VS Code supports version control with Git. You first need to install Git to power the Source Control panel. Download and install Git for Windows from the git-scm website. An Install Wizard is included that will ask you a series of questions about settings for your Git installation. We recommend using all of the default settings, unless you have a specific reason for changing something.

If you've never worked with Git before, GitHub Guides can help you get started. Python is an interpreted language. In contrast to compiled languages, in which the code you write needs to be translated into machine code in order to be run by your computer's processor, Python code is passed straight to an interpreter and run directly.

Administrator rights. Right-click on My Computer, choose Properties. Then find the Environment Variables button on Win7, it's under the Advanced tab; I forget where it is on other versions of Windows. Click that, and under System variables, edit the Path one.

Go back to your Python installation path folder and double-click on Scripts to open that directory. Next, copy its path from the path bar at the upper part of the windows besides the search bar , just like you did earlier for the Python installation path.

Once you've copied the Scripts path, head back to the Environment Variables. Next, select the Path variable and click on Edit. Type a semi-colon after your Python executable path and paste the Scripts path you just copied after it.

Then click Ok. Although this is just an alternative, and it's not necessary if you've added it in the Users variables already. To use the System Variables option, follow the steps highlighted above for copying the Python path and its Scripts path. Then head back into the Environment Variables. Then, inside the System Variables segment, locate a variable called Path.
