开始代码部分

一次性导入所需要的全部第三方库

import pandas as pd 
import pyecharts.options as opts
from pyecharts.charts import *
from pyecharts.globals import ThemeType#设定主题
from pyecharts.commons.utils import JsCode

1. 读取数据，而这些数据，一般都是我们爬取到的商品数据，或者公司内的数据库里面的数据

df1 = pd.read_csv(r'京东-乐高.csv', engine='python', encoding='utf-8-sig')
df2 = pd.read_csv(r'6K高达.csv', engine='python', encoding='utf-8-sig')
df3 = pd.read_csv(r'6K奥特曼.csv', engine='python', encoding='utf-8-sig')

查看下数据

df1.head(1)

2. 数据处理

把表格统计到一起

df_all = pd.concat([df1,df2,df3])
df_all.info()

除去重复值

df_all.drop_duplicates(inplace=True)

删除不必要的列

df_all = df_all.drop(['商品SKU','商品链接','封面图链接','评论链接','店铺链接','页码','当前时间','页面网址'],axis=1)
df_all.head(1)

筛选剔除广告

df_all = df_all[df_all['是否广告'] == '否']

重置索引

df_all = df_all.reset_index(drop=True)
df_all.info()

3. 处理完数据以后，我们就可以做可视化图表了
