kaggle数据集某咖啡店的营销数据分析
因为还处于数据分析的学习阶段（野生Python学者），所以在kaggle这个网站找了两个数据集来给自己练练手。准备工作
import pandas as pd
import os
import matplotlib.pyplot as plt
import numpy as np获取数据
这里我下载了两个数据集第一个是关于咖啡的销售情况，第二个是关于Instagram这个网站1000名最受欢迎的博主的数据。
我就从咖啡的销售情况这个表入手，因为我看了第二个表实在是没有什么眉目去做T.T
数据集文件放在最下方有需要的可以自行下载。
# 读取目录内的文件
directory = r'C:\Users\Admin\Desktop\demo\练习'
files = os.listdir(directory)
print(files)['coffee_result.csv', 'Instagram-Data.csv']# 存放文件
files_list = []
for file in files:
if file.endswith('.csv'):
directory_file = fr'{directory}\{file}'
files_list.append(directory_file)
print(files_list)['C:\\Users\\Admin\\Desktop\\demo\\练习\\coffee_result.csv', 'C:\\Users\\Admin\\Desktop\\demo\\练习\\Instagram-Data.csv']# 读取需要的文件
df = pd.read_csv(files_list)查看一些必要信息
df.info()

8通过info返回的信息可以看到card列存在一些空值，那我就把空值处理一下
df.isnull()] date datetime cash_type card money coffee_name 12 2024-03-02 2024-03-02 10:30:35.668 cash NaN 40.0 Latte 18 2024-03-03 2024-03-03 10:10:43.981 cash NaN 40.0 Latte 41 2024-03-06 2024-03-06 12:30:27.089 cash NaN 35.0 Americano with Milk 46 2024-03-07 2024-03-07 10:08:58.945 cash NaN 40.0 Latte 49 2024-03-07 2024-03-07 11:25:43.977 cash NaN 40.0 Latte ... ... ... ... ... ... ... 657 2024-05-31 2024-05-31 09:23:58.791 cash NaN 39.0 Latte 677 2024-06-01 2024-06-01 20:54:59.267 cash NaN 39.0 Cocoa 685 2024-06-02 2024-06-02 22:43:10.636 cash NaN 34.0 Americano with Milk 691 2024-06-03 2024-06-03 21:42:51.734 cash NaN 34.0 Americano with Milk 692 2024-06-03 2024-06-03 21:43:37.471 cash NaN 34.0 Americano with Milk 89 rows × 6 columns
空值是由支付类型为现金支付的那一列对应的行产生的
df['card'] = df['card'].fillna("-1")
df['card'].isnull().any()np.False_对数据进行处理
在info返回的信息看到date这一列的数值类型是对象，我就把它变成日期类型方便我自己后续操作
print(type(df.loc),type(df.loc))
df.loc<class 'str'> <class 'str'>
'2024-03-01'# 调整日期格式提取每行数据的月份
df['date'] = pd.to_datetime(df['date'])
df['datetime'] = pd.to_datetime(df['datetime'])
df['month'] = df['date'].dt.month
print(len(df['month'].unique()))7查看每月的销售情况
因为9月份的数据只有5天所以这个月就不纳入分析
# 查看每月的销量以及金额
df_six = df!=9].copy()
month = df_six['month'].unique() # 把月份单独拎出
month_sales = df_six.groupby('month')['money'].count()
month_sum = df_six.groupby('month')['money'].sum()
figure,axes = plt.subplots(1,2,figsize=)
figure.suptitle("Month sales and sum",size=20)
ax1 = axes.bar(month,month_sales)
axes.set_xlabel('Month',size=16)
axes.set_ylabel('Count',size=16)
ax2 = axes.bar(month,month_sum)
axes.set_xlabel('Month',size=16)
axes.set_ylabel('Sum',size=16)
axes.bar_label(ax1,fmt="%d",label_type="center")
axes.bar_label(ax2,fmt="%d",label_type="center")
plt.subplots_adjust(wspace=0.5)
统计每款咖啡的营销情况
每款咖啡每月的营销额
nrows,ncols = 2,4
figure3,axes = plt.subplots(nrows,ncols,figsize=,sharex=True,sharey=True)
coffee_month_sales = df_six.groupby(['month','coffee_name'])['money'].sum().reset_index(name='sum')
coffee_names = coffee_month_sales['coffee_name'].unique().tolist()
for idx,coffee_name in enumerate(coffee_names):
x,y = divmod(idx,ncols)
coffee_data = coffee_month_sales==coffee_name]
bars = axes.bar(coffee_data['month'],coffee_data['sum'])
axes.bar_label(bars,fmt="%d",label_type="center")
subtitle = f"{coffee_name} {int(coffee_data['sum'].sum())}"
axes.set_title(subtitle)
axes.set_xlabel('month',size=16)
axes.set_ylabel('sum',size=16)
figure3.suptitle('coffee month sales',size=20)
plt.tight_layout()
plt.subplots_adjust(wspace=0.5)
查看不同咖啡的受众人数以及占比
stati = df_six.groupby('coffee_name')['money'].count().reset_index(name='buyers')
stati.sort_values(by='buyers',ascending=True,inplace=True,ignore_index=True)
figure2,axes = plt.subplots(1,2,figsize=(16,8))
figure2.suptitle("Coffee audience number and proportion",size=20)
ax1 = axes.barh(stati.iloc[:,0],stati.iloc[:,1])
axes.bar_label(ax1,fmt="%d",label_type="center")
axes.set_ylabel("Kind",size=16)
axes.set_xlabel("Sum",size=16)
axes.pie(stati.iloc[:,1],labels=stati.iloc[:,0],autopct='%0.1f')
plt.subplots_adjust(wspace=0.5)
统计客户的实际消费情况
cardholder = df_six!='-1'].copy()
cardholder['tag'] = 1
cardholder.drop(columns=['date','datetime','cash_type'],inplace=True)
cardholder['month_sum'] = cardholder.groupby('card')['tag'].transform('sum')active_buyer = cardholder.groupby('card')['month_sum'].max().reset_index(name='buys')
active_buyer.sort_values(by='buys',inplace=True,ignore_index=True,ascending=False)
cardholder['money_sum'] = cardholder.groupby('card')['money'].transform('sum')
money_sum = cardholder.drop_duplicates(subset='card',ignore_index=True).copy()
money_sum.drop(columns=['money','coffee_name','month','tag','month_sum'],inplace=True)
money_sum.sort_values(by='money_sum',inplace=True,ignore_index=True,ascending=False)result = pd.merge(active_buyer,money_sum)
print('总消费金额平均数：',result['money_sum'].mean(),'\n',
result.head(10))总消费金额平均数： 75.29034111310592

程度大致就做到这种情况了，谢谢观看，如果有什么好的方法也可以在评论区评论！
