Why Can\'t I Run Python on Windows XP?

Unable to Recognize "python" as a Command

When attempting to run Python sample programs in a Windows XP environment after installing Python 2.7.2, you may encounter an error message indicating that "python" is not recognized as a command. To resolve this issue, the Python executable needs to be added to the Windows PATH variable.

Procedure:

1. Open "My Computer" and select "Properties."
2. Click on the "Advanced" tab.
3. Under "Advanced," select "Environment Variables."
4. In "System Variable," highlight "Path" and click "Edit."
5. Append the path to the Python executable (e.g., c:Python27) to the existing paths, separated by semicolons (;).
6. Click "Apply" to save the changes.
7. Restart the command prompt (cmd.exe).

Once the path is set correctly, the command "python" should be recognized, and you will be able to execute Python programs successfully.
