loop word

If a word is obtained by a circular right shift, we call these words a type of circular word.For example: picture and turepic belong to the same kind of cyclic word.Now given n words, we need to count how many kinds of cyclic words there are in the n words.
Input description:
Input consists of n+1 lines:

The number of words in the first line is n (1 ≤ n ≤ 50)

The next n lines, each line has a word word[i], length length (1 ≤ length ≤ 50).Consists of lowercase letters

Output description:
Output the number of loop words

explain
It doesn't have to contain two or more different words to be a cycle word!

n = int(input())words = []for i in range(n):words.append(input())def fun(s):ans = set()for i in range(len(s)):tmp = s[i:]+s[:span>i]ans.add(tmp)return ansres = []for word in words:if fun(word) not in res:res.append(fun(word))print(len(res))
