Visualization | Python analyzes Mid-Autumn mooncakes, these flavors are the yyds!

#Mid-Autumn Festival, also known as Moon Festival, Moonlight Festival, Moon Eve, Autumn Festival, Mid-Autumn Festival, Moon Worship Festival, Moon Niang Festival, Moon Festival, Reunion Festival, etc. are traditional Chinese folk festivals. Since ancient times, there have been folk customs such as worshiping the moon, appreciating the moon, eating moon cakes, playing with lanterns, admiring osmanthus, and drinking osmanthus wine, which have been passed down to this day and lasted for a long time. In this issue, we analyze the sales of Moubao Mid-Autumn Mooncakes to see

which flavors of mooncakes sell well

, Which places sell mooncakes well, I hope it will be helpful to my friends.

##Involved libraries:

Pandas

— Data processing

Pyecharts
— Data Visualization
jieba — participle
collections — Data statistics

Visualization part:

##Bar — Bar chart
Pie — Pie Chart
Map— Map
Stylecloud — Word Cloud

1. Import module

import re
import jieba
import stylecloud
import numpy as np
import pandas as pd
from collections import Counter
from pyecharts.charts import Bar
from pyecharts.charts import Map 
from pyecharts.charts import Pie
from pyecharts.charts import Grid
from pyecharts.charts import Page
from pyecharts.components import Image
from pyecharts.charts import WordCloud
from pyecharts import options as opts 
from pyecharts.globals import SymbolType
from pyecharts.commons.utils import JsCode

2. Pandas data deal with

2.1 Read data ##

df = pd.read_excel("月饼.xlsx")
df.head(10)

Copy after login

Result:

Visualization | Python analyzes Mid-Autumn mooncakes, these flavors are the yyds!

2.2 去除重复值

print(df.shape)
df.drop_duplicates(inplace=True)
print(df.shape)

Copy after login

(4520, 5)
(1885, 5)

Copy after login

一共有4520条数据，去重后还有1885条数据（某宝一个店铺会在不同页面推荐，导致重复数据比较多）。

2.3 空值处理

处理购买人数为空的记录：df[&#39;付款情况&#39;] = df[&#39;付款情况&#39;].replace(np.nan,&#39;0人付款&#39;)

Copy after login

2.4 处理付款情况字段

df[df[&#39;付款情况&#39;].str.contains("万")]

Copy after login

付款人数超过10000后会直接用"万"替代，这里我们需要将其恢复：

# 提取数值
df[&#39;num&#39;] = [re.findall(r&#39;(\d+\.{0,1}\d*)&#39;, i)[0] for i in df[&#39;付款情况&#39;]] 
df[&#39;num&#39;] = df[&#39;num&#39;].astype(&#39;float&#39;)

# 提取单位（万）
df[&#39;unit&#39;] = [&#39;&#39;.join(re.findall(r&#39;(万)&#39;, i)) for i in df[&#39;付款情况&#39;]] 
df[&#39;unit&#39;] = df[&#39;unit&#39;].apply(lambda x:10000 if x==&#39;万&#39; else 1)

# 计算销量
df[&#39;销量&#39;] = df[&#39;num&#39;] * df[&#39;unit&#39;]
df = df[df[&#39;地址&#39;].notna()]
df[&#39;省份&#39;] = df[&#39;地址&#39;].str.split(&#39; &#39;).apply(lambda x:x[0])

# 删除多余的列
df.drop([&#39;付款情况&#39;, &#39;num&#39;, &#39;unit&#39;], axis=1, inplace=True)

# 重置索引
df = df.reset_index(drop=True)

结果：

3. Pyecharts数据可视化

3.1 月饼商品销量Top10

代码：

shop_top10 = df.groupby(&#39;商品名称&#39;)[&#39;销量&#39;].sum().sort_values(ascending=False).head(10)
bar0 = (
    Bar()
        .add_xaxis(shop_top10.index.tolist()[::-1])
        .add_yaxis(&#39;sales_num&#39;, shop_top10.values.tolist()[::-1])
        .reversal_axis()
        .set_global_opts(title_opts=opts.TitleOpts(title=&#39;月饼商品销量Top10&#39;),
                         xaxis_opts=opts.AxisOpts(axislabel_opts=opts.LabelOpts(rotate=-30))) 
        .set_series_opts(label_opts=opts.LabelOpts(position=&#39;right&#39;))
)

效果：

商品名称太长显示不全，我们调整一下边距：

bar1 = (
    Bar()
        .add_xaxis(shop_top10.index.tolist()[::-1])
        .add_yaxis(&#39;sales_num&#39;, shop_top10.values.tolist()[::-1],itemstyle_opts=opts.ItemStyleOpts(color=JsCode(color_js)))
        .reversal_axis()
        .set_global_opts(title_opts=opts.TitleOpts(title=&#39;月饼商品销量Top10&#39;),
             xaxis_opts=opts.AxisOpts(axislabel_opts=opts.LabelOpts(rotate=-30)),
             ) 
        .set_series_opts(label_opts=opts.LabelOpts(position=&#39;right&#39;))
)
# 将图形整体右移
grid = (
    Grid()
        .add(bar1, grid_opts=opts.GridOpts(pos_left=&#39;45%&#39;, pos_right=&#39;10%&#39;)) 
)

这样是不是好多了。

还可以来些其他（比如：形状）设置：

3.2 月饼销量排名TOP10店铺

bar3 = (

    .add_xaxis(shop_top10.index.tolist())
    .add_yaxis(&#39;&#39;, shop_top10.values.tolist(),
               category_gap=&#39;30%&#39;,
              )

    .set_global_opts(
        xaxis_opts=opts.AxisOpts(axislabel_opts=opts.LabelOpts(rotate=-30)),
        title_opts=opts.TitleOpts(
