Example 1: python add unique to list

myList = ['Arise', 'But', 'It', 'Juliet', 'Who', 'already', 'and', 'and', 'and', 
     'breaks', 'east', 'envious', 'fair', 'grief', 'is', 'is', 'is', 'kill', 'light',

     'through', 'what', 'window', 'with', 'yonder']

auxiliaryList = []
for word in myList:
    if word not in auxiliaryList:
        auxiliaryList.append(word)

Example 2: python list with only unique values

my_list = list(set(my_list))

Example 3: unique list values python ordered

def get_unique(seq):
    seen = set()
    seen_add = seen.add
    return [x for x in seq if not (x in seen or seen_add(x))]

Example 4: how to find unique values in list in python

mylist = ['nowplaying', 'PBS', 'PBS', 'nowplaying', 'job', 'debate', 'thenandnow']
myset = set(mylist)
print(myset)

Example 5: how to find unique sublist in list in python

In [22]: lst = [[1,2,3],[1,2],[1,2,3],[2,3],[4,5],[2,3],[2,4],[4,2]]

In [23]: set(frozenset(item) for item in lst)
Out[23]: 
set([frozenset([2, 4]),
     frozenset([1, 2]),
     frozenset([2, 3]),
     frozenset([1, 2, 3]),
     frozenset([4, 5])])

Example 6: python count unique values in list

len(set(["word1", "word1", "word2", "word3"]))
# set is like a list but it removes duplicates
# len counts the number of things inside the set
