Counter в Python примеры

Counter является подклассом dict и является частью модуля Collections. Он используется для подсчета хешируемых объектов.

Это неупорядоченная коллекция, в которой элементы хранятся как ключи словаря, а их счетчики являются значениями.

Формат объекта счетчика:

Элементы подсчитываются из итерации или инициализируются из другого сопоставления (или счетчика)

Инициализация объекта Counter выполняется с помощью вызова Counter() .

Мы также можем передать итерацию в вызов и получить соответствующий сопоставленный объект.

Обратите внимание, что когда отображается объект Counter, пары ключ-значение отображаются в порядке убывания счетчика.

У объектов счетчика есть интерфейс словаря, за исключением того, что они возвращают нулевое количество пропущенных элементов вместо того, чтобы KeyError .

1. Подсчитайте количество отдельных элементов

Доступ к подсчетам отдельных элементов осуществляется так же, как и к подсчетам словаря, что означает, что counter_objectCounter value что значит дает количество key .

2. Установите количество элементов

Чтобы установить количество элементов, используйте counter_objectCounter value что значит = value . Если key не существует, он добавляется в словарь счетчиков вместе с новым счетчиком.

3. Удалить ключ из объекта Counter

Чтобы удалить ключ из объекта Counter, используйте del counter_objectCounter value что значит .

4. elements()

Этот метод возвращает итератор по элементам, значения которых повторяются столько раз, сколько их количество. Этот метод игнорирует все элементы, у которых счетчик меньше единицы.

5. most_common (n)

Это возвращает список из n наиболее распространенных элементов и их количество от наиболее распространенных до наименьших. Если n опущено или None , most_common() возвращает все элементы счетчика. Элементы с равным количеством упорядочиваются произвольно.

6. вычитание (итерация / отображение)

Это возвращает отображение / итерацию после вычитания содержимого двух итераций / отображений. Элементы не заменяются, а вычитается только их количество.

7. обновление (повторение / отображение)

Это похоже на subtract() , но только добавляет счетчики, а не вычитает их.

Другие методы Counter()

• counter.clear() используется для сброса счетчиков всех элементов в счетчике
• counter.values() возвращает объект dict-values, используемый другими методами, такими как sum() для получения общего количества всех элементов.
• list(counter) используется для перечисления всех уникальных элементов
• set(counter) преобразует счетчик в Set
• counter.items() возвращает список пар (key, value) в счетчике.
• counter += Counter() удаляет все элементы с нулевым или отрицательным счетом

Арифметические операции над счетчиками

Мы можем использовать основные арифметические операции со счетчиками, такие как сложение, вычитание, объединение и пересечение.
