使用代码：

import matplotlib.pyplot as plt
import pandas as pd

data = pd.read_csv('../data/data1.csv',encoding='gbk')
# print(data['商品'])
total = []
res = []
result = []
maxFiveNum = []
num = 0

def count(i):
    k = 0
    for i1 in data['商品']:
        if(i == i1):
            k = k + 1
    return k

for i in data['商品']:
    if(i not in total):
        number = count(i)
        if(len(maxFiveNum) < 5):
            maxFiveNum.append(number)
        elif(number > min(maxFiveNum)):
            maxFiveNum.append(number)
            maxFiveNum.remove(min(maxFiveNum))
        res.append([number, i])
        total.append(i)
for get in res:
    if (get[0] in maxFiveNum):
        result.append(get)
list.sort(result,reverse=True)
print(result)

得到结果：
