You're an idiot.
Well, no, but since you asked me to call you one ... actually the first time I got into ren'py games I had to ask the same qquestion. Lack of knowledge is not stupidity.
The console is opened by pressing shift-O. If that isn't working, it's because the console is disabled in a renpy file in yourgame folder.
Navigate to the game folder, subfolder "renpy," subfolder, "common" and find the file 00console.rpy
In that file, search for the line that says "config.console=false" .... now, if you're not an idiot you can probably guess what to do with that line, but just in case, the trick is to edit it to read "config.console=true" and you should find, next time you open the game, that shift+O now does open the console. Then you can type in the cheats as shown.
