Set Mutations

    Can someone help me debug this? I'm getting EOFError for the input of command. 

    # Enter your code here. Read input from STDIN. Print output to STDOUT
a = int(input())
A = set(map(int, input().split()))

N = int(input())
for i in range(2*N+1):
    command = list(map(str, input().split(' ')))
    S = set(map(int, input().split()))
    op = command[0]
    if op == 'intersection_update':
        A.intersection_update(S)
    elif op == 'difference_update':
        A.difference_update(S)
    elif op == 'update':
        A.update(S)
    elif op == 'symmetric_difference_update':
        A.symmetric_difference_update(S)
        
print(sum(A))
