Question

我的文字包含以下字符串：

{whatever}:::duplicateString:::{whatever}
{whatever}:::duplicateString:::{whatever}
....
{whatever}:::duplicateString:::{whatever}
{whatever}:::duplicateString:::{whatever}

如何从文本中删除 duplicateString ：主要想法是，如果它出现的次数超过一次，则从行中删除第二个单词。

第一个想法是逐行读取它们并按“ ::: ”拆分，以便创建数组并通过向TreeSet添加条目来迭代数组。好。但是如何再次粘合线？

我不记得任何机制来弄清楚这样的任务。语言没关系，只是解决方案？

示例文字：

Appliances:::Main
Appliances:::Main:::Appliance Warranties
Appliances:::Main:::Beer Keg Refrigerators
Appliances:::Main:::Beverage Refrigerators
Appliances:::Main:::Ceiling Fans & Accessories
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories:::Downrod Couplers
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories:::Downrods
Appliances:::Main:::Ceiling Fans & Accessories:::Accessories:::Fan Replacement Blades

理想情况下，它必须像：

Appliances:::Main
Appliances:::Appliance Warranties
Appliances:::Beer Keg Refrigerators
Appliances:::Beverage Refrigerators
Appliances:::Ceiling Fans & Accessories
Appliances:::Ceiling Fans & Accessories:::Accessories
Appliances:::Ceiling Fans & Accessories:::Accessories:::Downrod Couplers
Appliances:::Ceiling Fans & Accessories:::Accessories:::Downrods
Appliances:::Ceiling Fans & Accessories:::Accessories:::Fan Replacement Blades

如果duplicateString可能只作为第二个单词出现，你可以（在Python中）：

lastWord = None
for line in open('file.txt'):
  w = line.split(':::')
  thisWord = w[1]
  if lastWord==w[1]:
    del w[1]
  lastWord = thisWord
  print ':::'.join(w)

从文本中删除重复的单词
