Why i cannot import all functions using import itertools ?

Question

from itertools import count

for i in count(3):
print(i)
if(i>11):
break

Output:
3
4
5
6
7
8
9
10
11
12

********************************************************************************************************
But now using this:

import itertools

for i in count(3):
print(i)
if(i>11):
break

Output:
NameError: name 'count' is not defined

Why does this occur??
Thanking u in advance... :)
