	Which is exactly what you told it to do. You have defined a function
containing four statements: fwd(), print(), sleep(), and stop(); after
executing the stop the function will return to where it was called -- the
end of your program.

	All of your"if" statements will be executed after "loop" is defined
(but not executed) and before the call to "loop" at the bottom. They are
NOT part of "loop". Please reread the Python language reference manual,
focusing on the part that describes indentation and block structuring.


>loop()
>

	Also, just calling something "loop" does not make it a loop. This
function will be called just one time and then the program will exit.
