Time exceeded error in using cycle

Question

from itertools import cycle

for char in cycle("string"):
A = []
A.append(char)
print(char)
if len(A) == 7:
break

I wanted to print out
s
t
r
i
n
g
s
but it didn't work and time exceeded error occurred. What is the problem of this code?

Answer 1

You should initialize A before the loop, otherwise it will never get length of 7.

Answer 2

Thanks a lot. Now I realize that A is iteratively reassigned to an empty list.
