%definition of a function
def array_left_rotation(a, n, k):
b = a
for i in range (n):
a[(i-k)%n] = b[i]
return a;
n, k = map(int, raw_input().strip().split(' '))
a = map(int, raw_input().strip().split(' '))
answer = array_left_rotation(a, n, k);
print ' '.join(map(str,answer))
I have observed that list b is also changing on iteration even though it is defined outside the 'for' loop. Can someone tell me, is my assumption correct. if so please suggest the possible solution ?
