Python - add two-digits numbers

def solution(A):

    result = 0

    for number in A:
        if 9 < number < 100 or -100 < number < -9:
            result += number

    return result

# --- tests ---

data = [
  [ [1, 1000, 80, -91], -11 ],
  [ [2, 25, 300, 52, 10], 87 ],
]

for A, correct_result in data:
    result = solution(A)
    print(result, correct_result, result == correct_result)
