This tutorial will look into the multiple ways to bank check if Python is installed in Windows. We can check if Python is installed in Windows using three commands which are explained below.

Check if Python Is Installed in Windows Using the py Control

When we execute the py command in the Windows Command Prompt, it first displays the details of the latest version installed on the reckoner and and then runs/starts the installed version.

If we need to bank check if some version of Python, i.eastward., Python 2 or iii, is installed, we can do so using the post-obit control.

For Python two.x,

              py -2                          

For Python iii.vii,

              py -3.seven                          

If the specified version of Python is not installed, the command will kickoff return the not found fault and so render all the installed versions of Python installed by the py launcher.

              C:\WINDOWS\system32>py -2.five Python 2.five not found! Installed Pythons found by py Launcher for Windows  -3.8-32 *  -3.7-64  -2.seven-64  Requested Python version (two.v) not installed, use -0 for available pythons                          

And if the py launcher is not installed, the following error will be returned.

              'py' is not recognized equally an internal or external command, operable program or batch file.

The above command volition return the latest version installed on the estimator and volition not get-go it. We can also check if some specific version of Python is installed in the following way.

              py -2 --version                          

Information technology will return the latest version of Python 2 installed on the computer. If the Python version specified in the command is not installed, similar the py command, it volition return all the versions installed on the computer.

Check if Python Is Installed in Windows Using where Command

The Windows where control is used to search and display files in a directory tree. The command searches for the given pattern in the current directory and the paths specified in the PATH environment variable.

The where command is handy to locate the multiple versions of the same control in the PATH environs variable. Then, if we look for python using the where command, information technology will render the paths of all the copies of python.exe.

              C:\WINDOWS\system32>where python C:\Python27\python.exe C:\Users\Waiz\AppData\Local\Programs\Python\Python37\python.exe C:\Users\Waiz\AppData\Local\Programs\Python\Python38-32\python.exe                          

If Python is not installed on the estimator, the where control will return the following error.

              INFO: Could non notice files for the given blueprint(s).
