Leetcode 猜数字游戏 Python

算法基础真的是我的硬伤啊

大神的题解都是那么难看懂

每次点开正确答案只有三四句而自己敲了二三十行代码

都感觉自己的脑子是不是99新的

class Solution:
    def getHint(self, secret: str, guess: str) -> str:
        Bulls = 0
        Cows = 0
        s =  secret
        g = guess
        len_v = len(s)
        for i in range(0, len_v):
            if s[i] == g[i]:
                Bulls += 1
                s1 = list(s)
                s1[i] = "_"
                s = "".join(s1)
        slist = list(s)
        dic = Counter(slist)
        for i in range(0, len_v):

                continue
            if g[i] in dic and dic[g[i]] != 0:
                Cows += 1
                dic[g[i]] -= 1
        ansr = "%dA%dB" % (Bulls, Cows)
        return ansr
