從列表中刪除包含其他項目的所有項目 - Python

Question

我有一些列表，我想刪除包含其他項目的每個項目，除了項目本身。

例如：

如果我的列表看起來像這樣：

[“AAA”，“STACK_OVERFLOWAAAAAAAA”，“123AAAAA45678”，“123456”，“FOO”，“DIR”，“ITEM”，........]

現在，我希望代碼將刪除其中包含“AAA”的所有項目。 在那次掃描之后，我希望代碼將刪除其中包含“123456”的所有項目（如果有的話），依此類推。

想要的輸出應該是這樣的：

lst = [“AAA”，“123456”，“FOO”，“DIR”，“ITEM”，........]

這是我的代碼，由於某種原因，它不起作用......

lst = ["AAA",
   "STACK_OVERFLOWAAAAAAA",
   "123AAAAA45678",
   "123456",
   "FOO",
   "DIR",
   "ITEM"
   "AAAAA1234",
   "VDFKGMGDFRAAAAAAAAAA",
   "FNHBFDGBNDFGFHFGDUHGDRGJRAAAAAAAAA",
   "6545154DDFEFRGAAAAAAA",
   "123",
   "ABC",
   "abc"]

# The meaning of this variable is to indicate if the sub - item has already found in the list.
# If so, the code should remove all the next items which contains the current sub - item
AlreadyFound = False

# ItemToSearch = the sub - item which the program should search in the other list - items.
for ItemToSearch in lst:

    # Start the loop and search the sub - item in every item which in the list.
    for ItemToCheck in lst:

        # If the current item contains the sub - item..
        if (ItemToSearch in ItemToCheck):

            # If the sub - item has already found in the list
            if (AlreadyFound == True):

                # Delete the current item from the list
                del CurrItem
            else:
                AlreadyFound = True

print "\n".join(lst)
input()

我很樂意得到一些幫助。 謝謝。

這應該這樣做：

>>> lst = ["AAA", "STACK_OVERFLOWAAAAAAA", "123AAAAA45678", "123456", "FOO", "DIR", "ITEM"]
for i, x in enumerate(lst):
    lst[i+1:] = [y for y in lst[i+1:] if x not in y]
...     
>>> lst
['AAA', '123456', 'FOO', 'DIR', 'ITEM']
>>>
