无论如何，当我运行时，Python总是打印一个值

Question

它总是打印"2〃；，请帮帮我这是我的代码：

ketqua1 = randint(1,6)
ketqua2 = randint(1,6)
ketqua3 = randint(1,6)
computer = ketqua1 + ketqua2 + ketqua3
if 10 < computer <= 18:
computer = 1
elif computer <= 10:
computer = 2

您的代码是随机运行的。这意味着有一个变化，你会在一天、一周、一个月内得到相同的答案。

假设您有from random import randint然后你可以这样做：

def execute():
ketqua1 = randint(1,6)
ketqua2 = randint(1,6)
ketqua3 = randint(1,6)

computer = ketqua1 + ketqua2 + ketqua3
if 10 < computer <= 18:
computer = 1
elif computer <= 10:
computer = 2
return computer
histogram = [0,0,0]
for _ in range(100):
c = execute()
histogram[c] += 1
print("Times we got computer==1: {}".format(histogram[1]))
print("Times we got computer==2: {}".format(histogram[2]))

你应该有这样的东西：

Times we got computer==1: 49
Times we got computer==2: 51

所以randint被很好地利用了。。。
