equivalent to Tcl 'after' command?

[Mark Harrison]

I'm writing some event-driven programs, and I would like
to do the equivalent of the Tcl 'after' command, e.g.:

	after 1000 {puts "one second has elapsed"}

1.  What's the most canonical way of doing this?

2.  What's the best reference that talks about non-gui event loop
    programming in Python?

Many TIA!
Mark
