#Running from command line

To run python from the command line in windows, it must be added to the PATH environment variable.
Depending on the version of windows, finding the PATH variable is slightly different.

Windows 8
Click on Control Panel > System > Advanced
Click on Environment Variables, under System Variables, find PATH, and click on it, then click the edit button.

Windows 7
Select Computer from the Start menu
Choose System Properties from the context menu
Click Advanced system settings > Advanced tab
Click on Environment Variables, under System Variables, find PATH, and click on it, then click the edit button

Windows XP
Start > Control Panel > System > Advanced
Click on Environment Variables, under System Variables, find PATH, and click on it, then click the edit button.

Add Python directory to the end of the PATH variable by adding
C:PythonXX;

(where XX is the first two numbers of the version) to the end of the variable.

Make sure that there is a semi colon before the C:PythonXX;
