“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

in PowerShell enter this:

[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User")

Close PowerShell and then start it again to make sure Python now runs. If it doesn’t, restart may be required.
