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
复制代码 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)
复制代码- ['coffee_result.csv', 'Instagram-Data.csv']
复制代码- # 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)
复制代码- ['C:\\Users\\Admin\\Desktop\\demo\\练习\\coffee_result.csv', 'C:\\Users\\Admin\\Desktop\\demo\\练习\\Instagram-Data.csv']
复制代码- # 读取需要的文件
- df = pd.read_csv(files_list[0])
复制代码 查看一些必要信息
- <class 'pandas.core.frame.DataFrame'>

- len(df['coffee_name'].unique().tolist()))
复制代码- ['card', 'cash']

复制代码 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 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()
复制代码 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[1,'date']),type(df.loc[1,'datetime']))
- df.loc[1,'date']
复制代码- <class 'str'> <class 'str'>
- '2024-03-01'
复制代码- # 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()))
复制代码 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[df['month']!=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=[16,8])
- figure.suptitle("Month sales and sum",size=20)
- ax1 = axes[0].bar(month,month_sales)
- axes[0].set_xlabel('Month',size=16)
- axes[0].set_ylabel('Count',size=16)
- ax2 = axes[1].bar(month,month_sum)
- axes[1].set_xlabel('Month',size=16)
- axes[1].set_ylabel('Sum',size=16)
- axes[0].bar_label(ax1,fmt="%d",label_type="center")
- axes[1].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=[16,8],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_month_sales['coffee_name']==coffee_name]
- bars = axes[x,y].bar(coffee_data['month'],coffee_data['sum'])
- axes[x,y].bar_label(bars,fmt="%d",label_type="center")
- subtitle = f"{coffee_name} {int(coffee_data['sum'].sum())}"
- axes[x,y].set_title(subtitle)
- axes[x,y].set_xlabel('month',size=16)
- axes[x,y].set_ylabel('sum',size=16)
-
- figure3.suptitle('coffee month sales',size=20)
- plt.tight_layout()
- plt.subplots_adjust(wspace=0.5)
复制代码
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[0].barh(stati.iloc[:,0],stati.iloc[:,1])
- axes[0].bar_label(ax1,fmt="%d",label_type="center")
- axes[0].set_ylabel("Kind",size=16)
- axes[0].set_xlabel("Sum",size=16)
- axes[1].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[df_six['card']!='-1'].copy()
- cardholder['tag'] = 1
- cardholder.drop(columns=['date','datetime','cash_type'],inplace=True)
- cardholder['month_sum'] = cardholder.groupby('card')['tag'].transform('sum')
复制代码- 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)
复制代码- result = pd.merge(active_buyer,money_sum)
- print('总消费金额平均数:',result['money_sum'].mean(),'\n',
- result.head(10))
复制代码- 总消费金额平均数: 75.29034111310592

复制代码 通过打印的数据可以看到这算是最活跃的一批用户了
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!
