time modul hasn't got a function like that. I believe it's unlikly any
modul ever contains one, because it's easily done and things like "print
to stdout" arn't of general value (for example in GUI programming).
A simple function is:
for n in range(amount, 0, -1):
This isn't absolutly accurate, but enough for a 60 sec countdown. The
whole trick is the range function with negative third argument.
You might want to print the countdown on one single line. This can be
print " %i\033[A" % n
"\033[A" is ANSI for "one line up" (print's newline will then going back
to the line and to its beginning)
