Python：将文件中的单词合并到一行

Question

I have a list with words out of different textfiles. When I sort this list out and clean them of duplicates I still see multiple words which are the soms but out of different text files, eg ['you', 'chainletter.txt'] and ['you', 'grail.txt'] My question is , how could I combine these to give the output ['you', 'chainletter.txt', 'grail.txt']

I'm currently using the following code: 'pearl' module:

def make_table(pairs):
    import sort
    import dup
    sort = sort.merge_pairs(pairs)
    nodup = dup.remove_dups(sort)
    print(nodup)
    return nodup

And i want my 'search engine' to display words like described above

I'm not quite sure what you're trying to achieve overall, but the two problems you mention can be solved as follows:

1. You can use set() to remove duplicates from a list (and list() to turn it back into a list if you like).

2. To add the elements of a list into another list, use .extend()

This question about merging lists may also be of interest.
