hope this fix your issue If you just want to remove duplicates, then you can use set() and convert back to a list:

'abcTable : [os : set1] [origin : tag2] [os_version : p8] [0000_id : unknown] [cust : 75sa] [model : tt_xy2U] [manufacturer : what] ']

    # We use tuples because they are hashable
    lookup = tuple(row[:3])    
    if lookup not in added_keys:

like below fixes the issue Although your hash-table implementation could be made more concise, readable, and idiomatic, with a small boost in speed, I suspect that isn't what your interviewer was disappointed in.
More likely, he pushed you for a better solution in hopes that you would come up with an argument why your solution was effectively optimal, but instead, you searched for a while and gave up.

wish of those help Say I have a list K, and a list B. If an entry in K fulfills my condition x, I want the index of that entry in my list B.

for n, item in enumerate(k):
    if item == x:

it helps some times You can use some handy Linq extension methods to get the job done. SelectMany will flatten the lists and select all the items, and Distinct will remove any duplicates:
List<string> mergedLists = ListsToMerge.SelectMany(x => x).Distinct().ToList();
