Dataset‘Northwind’。

Dataset ‘Northwind’”翻译为“数据集‘北风’”，可以通过以下代码示例来创建该数据集：

import pandas as pd

# 读取 Northwind 数据集的各个表格文件
categories = pd.read_csv('Northwind/categories.csv')
customers = pd.read_csv('Northwind/customers.csv')
employees = pd.read_csv('Northwind/employees.csv')
orders = pd.read_csv('Northwind/orders.csv')
order_details = pd.read_csv('Northwind/order_details.csv')
products = pd.read_csv('Northwind/products.csv')
regions = pd.read_csv('Northwind/regions.csv')
shippers = pd.read_csv('Northwind/shippers.csv')
suppliers = pd.read_csv('Northwind/suppliers.csv')
territories = pd.read_csv('Northwind/territories.csv')

# 将各个表格合成一个数据集
northwind = {
    'categories': categories,
    'customers': customers,
    'employees': employees,
    'orders': orders,
    'order_details': order_details,
    'products': products,
    'regions': regions,
    'shippers': shippers,
    'suppliers': suppliers,
