Answer 1

Here's a possible solution:

string_list = ['rest', 'resting', 'look', 'looked', 'it', 'spit']
def string_set(string_list):
    return set(i for i in string_list 
               if not any(i in s for s in string_list if i != s))

print(string_set(string_list))

prints out:

set(['looked', 'resting', 'spit'])

Note I create a set (using a generator expression) to remove possibly duplicated words as it appears that order does not matter.
