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',
'moon', 'pale', 'sick', 'soft', 'sun', 'sun', 'the', 'the', 'the',
'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
