Running Python from the terminal is often unavoidable. However, if you just installed Python on Windows 10 for the first time, running it via the Windows Terminal is only possible if it's added to the Windows PATH environment variable. It can seem tricky to do, but it's nothing to fear. To help you overcome the twists involved in adding Python to the Windows PATH after installing it, let's take a look at the options and the few steps involved.
If you fail to add Python to the PATH on your Windows OS, you can't run the Python interpreter, start a virtual programming environment , or run commands like pip install from the terminal.
That's because, when you run any non-default program from the command line, the machine looks for an executable in the current folder, or in the Windows PATH. If it's not in the PATH variable, the terminal returns a "command not found" error. Adding to the PATH is powerful, even if you're executing a command from a created or default batch file , adding its parent execution file to the PATH variable makes it callable from the terminal as well.
First off, if you've not installed Python on your machine, go to the python. Open up your terminal and type python , then hit the Enter key. The command might return an error that says "'python' is not recognized as an internal or external command, operable program or batch file," indicating that Python isn't added to your machine's PATH variable yet.
To do that, open up the Windows search bar and type python. Then right-click on Python. In the Explorer windows that opens, click on the long directory bar to the left of the search bar. Then continue with the next steps below. Once in the properties menu, click on the Advanced system settings option. In the next window, select the Advanced tab, and select Environment Variables.
The Environment Variables menu has two distinct parts: an upper part called User variables , and a lower part named System variables. However, our focus is on the User variables in this case. Within the User variables menu, locate a variable called Path. However, if you can't find that variable, you might need to create it. To do that, click on New. Next, in the Variable name form, type Path , and paste your Python path in the Variable value field.
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. Click on that variable and click on Edit. In the next window that comes up, click on New and paste the path you copied earlier in the opened space.
Repeat that process for the Scripts path as well. Next, click Ok and close the Environment Variables window. Although using this method doesn't work in all cases, you can still give it a try. To do that, click on your installation file and check the Add Python 3.
The version number will change when installing different versions of Python. That means you can start running Python commands via the command line immediately after installation. If the command returns the currently installed version of Python, it means you've successfully added it to the Windows PATH.
However, to check if you've added the Scripts directory to the Windows PATH, try to run pip install package on the terminal, replacing "package" with your preferred library.
If you've installed Python 2. For instance, managing a project with Sublime Text is easy when you open the terminal to the directory of your project folder and run the subl. This opens the editor in your current folder and displays it in the sidebar, another time-saving shortcut for working productively with Sublime Text.
