[已解决]关于字典报错

1005663861

from random import randint


def dice():
    a = randint(1, 6)
    b = randint(1, 6)
    c = a + b
    return c


def main():
    frequency = {2: 2.78, 3: 5.56, 4: 8.33, 5: 11.11, 6: 13.89, 7: 16.67,
                 8: 13.89, 9: 11.11, 10: 8.33, 11: 5.56, 12: 2.78}
    true_frequency = {2: 0, 3: 0, 4: 0, 5: 0, 6: 0, 7: 0,
                 8: 0, 9: 0, 10: 0, 11: 0, 12: 0}
    time = int(input('please enter the times:'))
    for i in range(0, time):
        if frequency.keys() == dice():
            true_frequency[dice()] += 1
    time = float(time)
    for num, times in true_frequency:
        true_frequency[num] = times / time


if __name__ == '__main__':
    main()

在执行这个程序的时候，会报错TypeError: cannot unpack non-iterable int object，不知道是什么原因，请大神指点。
