优化if.py

long_string = "This is a very long string!"

# 将多个if判断转化为数组，keys中多个元素为and关系
conditions = [
    {"keys": ["Andy"], "result": "string1"},
    {"keys": ["Jack"], "result": "string2"},
    {"keys": ["Jim","Mike"], "result": "string3"},
]

def find_result():
    for condition in conditions:
        result = False
        for key in condition["keys"]:
            if key in long_string:
                result = True
                break
        if result:

优化查找.py

    def __init__(self,word):
        self.word = word

    def pushChar(self,char):
        # 一个个字符往里塞，当塞入的最近 len(self.word) 个字符连起来等于初始化时的self.word 的话 .hint() 返回成功，具体判断逻辑懒得写了zzz
        pass

    def hit(self):
        return random.choice([True, False])

def find_result2():
    fuckAndy = FuckWord("Andy")
    fuckJack = FuckWord("Jack")
    fuckJim = FuckWord("Jim")
    fuckMike = FuckWord("Mike")

    for char in long_string:

        fuckJack.pushChar(char)
        fuckJim.pushChar(char)
        fuckMike.pushChar(char)
        # 防止Andy存在的时候白白完整遍历了整个字符串
        if fuckAndy.hit():
