关于字典报错
from random import randintdef 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 += 1
time = float(time)
for num, times in true_frequency:
true_frequency = 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。 for num , times in true_frequency :
改为：
for num , times in true_frequency . items() :
