Example 1: counter method in python
from collections import Counter
list1 = ['x','y','z','x','x','x','y','z']
print(Counter(list1))
Example 2: collections.counter in python
>>> from collections import Counter
>>>
>>> myList = [1,1,2,3,4,5,3,2,3,4,2,1,2,3]
>>> print Counter(myList)
Counter({2: 4, 3: 4, 1: 3, 4: 2, 5: 1})
>>>
>>> print Counter(myList).items()
[(1, 3), (2, 4), (3, 4), (4, 2), (5, 1)]
>>>
>>> print Counter(myList).keys()
[1, 2, 3, 4, 5]
>>>
>>> print Counter(myList).values()
[3, 4, 4, 2, 1]
Example 3: import counter python
from collections import Counter
Example 4: counter in python
$ python collections_counter_init.py
Counter({'b': 3, 'a': 2, 'c': 1})
Counter({'b': 3, 'a': 2, 'c': 1})
Counter({'b': 3, 'a': 2, 'c': 1})
Example 5: counter in python
import collections
print collections.Counter(['a', 'b', 'c', 'a', 'b', 'b'])
print collections.Counter({'a':2, 'b':3, 'c':1})
print collections.Counter(a=2, b=3, c=1)
Example 6: counter in python
from collections import Counter
x = Counter (a = 2, x = 3, b = 3, z = 1, y = 5, c = 0, d = -3)
for i in x.elements():
print( "% s : % s" % (i, x[i]), end ="\n")
