如何查找最长连续字符串

查找最长连续子字符串，子字符串须满足：由连续同字符组成

# 统计结果：字符：连续出现最多的次数
result = {}

# 统计连续出现的字符
def test(s):
    count = 0
    for c in s:
        if c == s[0]:
            count+=1
        else:
            break

    # 只统计最多出现的次数
    if result.get(s[0],0) < count:
        result[s[0]] = count

s1 = 'abbbbbbcccddddddddddddddddeee'
index = 0
while index<len(s1):
    substr = s1[index:]
    test(substr)
    index+=1

print('统计结果',result)

# 对结果进行排序
result_order = sorted(result.items(),key=lambda x:x[1],reverse=True)
print(result_order)
print(result_order[0])

运行结果：

统计结果 {'a': 1, 'b': 6, 'c': 3, 'd': 16, 'e': 3}
[('d', 16), ('b', 6), ('c', 3), ('e', 3), ('a', 1)]
('d', 16)
