如何在python中检查列表中连续字符的长度？

def check_consecutive_length(lst):
    max_length = 0
    current_length = 1

    for i in range(1, len(lst)):
        if lst[i] == lst[i-1]:
            current_length += 1
        else:
            max_length = max(max_length, current_length)
            current_length = 1

    max_length = max(max_length, current_length)
    return max_length

# 示例用法
my_list = [1, 1, 2, 2, 2, 3, 4, 4, 5, 5, 5, 5]
consecutive_length = check_consecutive_length(my_list)
print("最长连续字符的长度为:", consecutive_length)
