Python中列表所有元素的频率 [英] frequency of all elements of list in Python

问题描述

我有一个列表 l = [1,2,2,3,1,1,2,3,4,5,6]
我不想使用 l.count(element) 方法.我不想用于循环或迭代器.
像 {1: 3, 2: 3, 3: 2, 4: 1, 5: 1, 6: 1}

I have a list l = [1,2,2,3,1,1,2,3,4,5,6]
I don't want to use l.count(element) method. I don't want to use for loop or iterator.
output like {1: 3, 2: 3, 3: 2, 4: 1, 5: 1, 6: 1}

推荐答案

使用集合的Counter:

>>> from collections import Counter
>>> l = [1,2,2,3,1,1,2,3,4,5,6]
>>> Counter(l)
Counter({1: 3, 2: 3, 3: 2, 4: 1, 5: 1, 6: 1})
