The Python executable must be found in your system path, that is why you are unable to just simply type python at anytime at a command prompt. Simple fix: click Start > Control Panel > System > Advanced > Environment Variables (bottom right) Then you will have two list boxes one for user environment variables another for system variables. I prefer placing the path in the System environment variables section that way it is available for all accounts on the system (provided you have more than 1 user on it). In the System list locate the Path variables, select edit variable and append ;C:\Python25 to it. And thats it reopen a new command prompt the type python and it should just fire up. Hope this helps.
