Looking at this just made me realise that IDLE (Python IDE) inserts four spaces instead of tab when you indent using the tab key. I've always used tabs (1 tab = 1 level of indentation) for my personal projects, and only just realised why IDLE's "tabs" seem short by default.

Most IDEs I use have 1 tab = 4 spaces visually at least as their default though. It's only old Unixy tools (e.g. Emacs) that default to 8 space tab display.
