“python” not recognized as a command

Question

I just downloaded and installed Python 2.7.2 to my laptop and I am trying to run some sample programs. My laptop is running Windows XP.

When I open a cmd

Answer 1

This is because the Python exec are not in the search path of your operating system. In windows, start CMD. Type in

setx PATH PythonPath

where PythonPath is usually C:\Python27 or C:\Python33 or C:\Users\\AppData\Local\Programs\Python\Python37 depending on your Python version. After restarting the CMD, you should get see outcomes when typing

Python --version
