我有两个包含单词的字符串： 'dan esh gah'和'da nesh gah'

我需要交叉词，就是'gah'在这种情况下。

我用了这个代码

vocab=['dan esh gah']
gold=['da nesh gah']
s1 = ''.join(vocab)
s2=''.join(gold)

a=[]
track=[]
for k in range(len(s1)+1):
    if k!=0:
        for ka in range(0,len(s1)+1,k):
            if s1[ka:ka+k] in s2:
                track.append((len(s1[ka:ka+k])+1,s1[ka:ka+k]))
intersect=max(track)[1]
print(intersect)

但答案是错误的：

vocab=['dan esh gah']
gold=['da nesh gah']
s1 = ''.join(vocab)
s2=''.join(gold)

a=[]
track=[]
for k in range(len(s1)+1):
    if k!=0:
        for ka in range(0,len(s1)+1,k):
            if s1[ka:ka+k] in s2:
                track.append((len(s1[ka:ka+k])+1,s1[ka:ka+k]))
intersect=max(track)[1]
print(intersect)

请帮我解决这个问题。
