# Counting occurrence of an item in a list

Consider the following list:

``` lists = [1,5,3,5,5] ```

To count the number of a value (5 in this case) in a list:

``` print(lists.count(5)) 3 ```

# Counting occurrence of each item in a list

We can use `Counter` within the `Collections` module to count the occurrences of each item in a sequence.

To count occurrences of each item in `my_list`:

``` from collections import Countermy_list = ['a', 'b', 'b', 'c', 'c','c']occurrences = Counter(my_list)print(occurrences) Counter({'c': 3, 'b': 2, 'a': 1}) ```

We can see that `'c'` appears 3 times, `'b'` appears 2 times and `'a'` appears once in `my_list`.
