paragraph = " ".join(['a', 'c', 'b'] * 100000), banned = ["a", "b"]
这个测试用例不正确吧，parag ...

是字符串啊

1. >>> type(" ".join(['a', 'c', 'b'] * 100000))
   
2. <class 'str'>

解答错误

输入：paragraph = "Bob", banned = []
输出："Bob"
预期结果："bob"

今天有新题吗

谨行的小罗

def func335(paragraph, banned):
    paragraph = paragraph.lower()
    for each in banned + list("!?',;."):
        paragraph = paragraph.replace(each.lower(), '')
    result = paragraph.split()
    return max(result, key=result.count)

拉了盏灯

有点小激动呢，

阴阳神万物主

来一个马后炮。

1. def solve(paragraph:str,banned:'list of str')->str:
   
2.     tp = "!?',;."
   
3.     for each in tp:
   
4.         paragraph = paragraph.replace(each,' ')
   
5.     while '  ' in paragraph:
   
6.         paragraph = paragraph.replace('  ',' ')
   
7.     paragraph = paragraph.lower()
   
8.     words = paragraph.split()
   
9.     unbanned = []
   
10.     for word in set(words):
    
11.         if word not in banned:
    
12.             unbanned.append((word,words.count(word)))
    
13.     return sorted(unbanned,key=lambda x:x[1],reverse=True)[0][0]
    
14. if __name__ == '__main__':
    
15.     print('示例1 输出：',repr(solve("Bob hit a ball, the hit BALL flew far after it was hit.",['hit'])))
    
16.     print('示例2 输出：',repr(solve("a a a b b c c d",["a","b"])))

同时敲两种语言太累了，我老想末尾打分号

其实python允许末尾有分号……
