In Python, string.count(substring, start, end) is used to count the occurrences of a character or a substring in the given input string.
最后,返回`max_count`即可得到字符串中连续出现字符的最大次数。 下面是一个完整的实现代码示例: ```python def max_occurrences(string): count = 1 max_count = 1 for i in range(1, len(string)): if string[i] == string[i-1]: count += 1 else: max_count = max(count, max_count) ...
