Given an array of strings, group anagrams together.

Example:

Input: ["eat", "tea", "tan", "ate", "nat", "bat"], Output: [ ["ate","eat","tea"], ["nat","tan"], ["bat"] ] Note:

All inputs will be in lowercase. The order of your output does not matter

My code:

class Solution:
    def groupAnagrams(self, strs):
        """
        :type strs: List[str]
        :rtype: List[List[str]]
        """
        result=collections.defaultdict(list)
        for item in strs:
            tmp_list=[]
            for i in range(len(item)):
                tmp_list.append(item[i])
            tmp_list.sort()
            reform_str=str(tmp_list)
            
            result[reform_str].append(item)
        record=[]
        for item in result.keys():
            record.append(result[item])
        return record
