如何在python中找到一行中重叠子字符串的最大数量？

def get_overlap_substrings(string):
    substrings = []
    n = len(string)
    for i in range(n):
        for j in range(i+1, n+1):
            substrings.append(string[i:j])
    return substrings

def get_max_overlap_count(string):
    substrings = get_overlap_substrings(string)
    max_count = 0
    for substring in substrings:
        count = string.count(substring)
        if count > max_count:
            max_count = count
    return max_count

line = "ababab"
max_overlap_count = get_max_overlap_count(line)
print("最大重叠数量：", max_overlap_count)
