Why does "none" show?

Question

"none" shows before each number in output when I use time.sleep(1) in print function. how come? how can I fix this?

import time

i = 0
while 1==1:
print(time.sleep(1),i)
i = i + 1
if i >= 6:

break

f = 6
while 6>-1:
print(time.sleep(1),f)
f = f -1
if f == -1:

print("Finished")
break

Answer 1

One does not simply print time.sleep() it's a void method that returns none

Answer 2

if you just want it to cout to 6 and then back to 0 remove time.sleep(1) from print and put it on the line above the print statement.
