python获取数组中最多的元素

sample = [1,2,3,3,3,4,5,5]
max(set(sample), key=sample.count)

from collections import Counter

sample = [1,2,3,3,3,4,5,5]
data = Counter(sample)
data.most_common(1)[0][0]
# data.most_common(1)[0][1] # 就是相应的最高频元素的频次

from statistics import mode

mode(sample)

>>> a = [1,1,1,1,2,2,2,2,3,3,3,1,1,2,3,1,3,1,3,1,3,1,2,3,1,3]
>>> a
[1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 1, 1, 2, 3, 1, 3, 1, 3, 1, 3, 1, 2, 3, 1, 3]

>>> set(a)
{1, 2, 3}
>>> a.count(1)
11
