我想在python中为mindgame做一个AI。但是在这个函数中它甚至没有启动for循环。谁能知道为什么？

不同（）函数中的while循环不执行任何操作，而while（0）将阻止循环运行。即使它会运行，你的different（）函数也总是返回false。至少在最后一个循环中，它会将digit_list [3] == digit_list [3]作为两个循环范围进行比较，直到3.这始终为true，函数将返回false。因此，永远不会输入主循环中的代码。

def different(number):
    digit_list = [0] * 4
    i = 0
    while i:
        digit_list[i] = number%10
        number /= 10
        i += 1

    for x in range(0,3):
        for y in range(x+1,3):
            if digit_list[x] == digit_list[y]:
                return False
    return True

试试这个：

import random

def different(num):
    digits = []
    while num >= 1:
        cur = num%10
        if cur in digits:
            return False
        digits.append(cur)
        num = (num - cur) / 10
    return True

for i in range(0, 10000):
    rand = random.randrange(1000, 10000)

    if not different(rand):
        print(rand)

Python没有启动循环
