Question

大家好，我正在leetcode上练习Python编码问题：

https://leetcode.com/problems/remove-duplicates-from-sorted-array/description/

这是我的代码：

class Solution:
    def removeDuplicates(self,nums):
          result = []
          result.append(nums[0])
          for n in range(len(nums)):
            result_ref = False
            for x in range(n):
              if nums[x] == nums[n]:
                result_ref = False
              else:
                result_ref = True
            if result_ref:
              result.append(nums[n])
            else:
              continue

          return result

该功能在我的计算机上可以正常工作，但是我一直在我的leetcode控制台中收到此错误。有人知道如何解决吗？非常感谢你！

TypeError: slice indices must be integers or None or have an __index__ method
Line 25 in integerListToString (Solution.py)
Line 42 in main (Solution.py)
Line 48 in <module> (Solution.py)

Answer 1

请查看默认代码@ https://leetcode.com/problems/remove-duplicates-from-sorted-array/description/

class Solution(object):

    def removeDuplicates(self, nums): 

        """
        :type nums: List[int]
        :rtype: int
        """

rtype应该为int，但您返回布尔值

将“结果”更改为int时，该结果将消失：

TypeError: slice indices must be integers or None or have an __index__ method

btw afaik Python 2太旧了-imo Python 3.x更加有趣；）
