Python timer not working in real time -

i writing countdown in python doesn't work.

for countdown in 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, quit():     print (countdown) 

that's code. countdown zooms , quits program. there way make countdown comply real time , countdown , quit in 10 seconds. not immediately.

you need tell wait otherwise run code fast processor can it.

from time import sleep countdown in range(10,0,-1):   print(countdown)   sleep(1)
