python统计两个字符串从首字符开始最大连续相同的字符数

在python中统计两个字符串从首字符开始最大连续相同的字符数,函数如下:

def get_num(s1, s2):
    num = 0
    len_s1 = len(s1)
    list_s1 = []
    for i in range(len_s1):
        two_s1 = s1[0:i+1]
        list_s1.append(two_s1)
    for i in list_s1:
        if s2.startswith(i) and len(i) > num:
            num = len(i)
    return num
