如何在这个问题中处理报价问题？

class Solution:
    # @param strs: A list of strings
    # @return: A list of strings
    def anagrams(self, strs):
        # write your code here
        dic = {}
        result = []

        for s in strs:
            if s == '""':
                key ='""'
            else:
                key = ''.join(sorted(s))
            dic[key].add(s)
        for key, value in dic.iteritems():
            if len(value) > 1:
                result.append(value)
        return result

输入

["",""]

预期

["",""]

错误消息

Traceback (most recent call last): File "Main.py", line 7, in ans = Solution().anagrams(strs) File "Solution.py", line 14, in anagrams dic[key].add(s) KeyError: '' EXITCODE=1

当您编写["",""]时，输入数组的元素是空字符串 - ""不是字符串内容的一部分。因此s = '""'将无法与之匹配。你需要写：

if s == '':
