Python笔记(二)查找重复元素

一、查找数列重复元素---count()

>>> list = [,,,,,,,,,,,]

>>> set = set(list)

>>> for item in set:

         print("the %d has found %d" %(item,list.count(item)))

#输出
#the  has found
#the  has found
#the  has found
#the  has found 

二、查找重复元素，使用 Counter

>>> from collections import Counter

>>> Counter([1,2,2,2,2,3,3,3,4,4,4,4])

#输出
#Counter({2: 4, 4: 4, 3: 3, 1: 1})
