以下是一个使用 Python 完成处理某公司一周内三种电子产品（电脑/手机/平板）销售数据任务的示例代码，其中包含了字符串与列表操作、数值运算、字典操作、列表加循环以及集合操作： ```python # 示例数据：一周内三种电子产品（电脑/手机/平板）各天的销售量 sales_data_A = { "电脑": [10, 12, 8, 15, 9, 11, 7], "手机": [20, 22, 18, 25, 19, 21, 17], "平板": [5, 6, 4, 7, 3, 5, 2] } sales_data_B = { "电脑": [8, 10, 6, 12, 7, 9, 5], "手机": [18, 20, 16, 22, 17, 19, 15], "相机": [3, 4, 2, 5, 1, 3, 2] } # 产品单价 prices = { "电脑": 5000, "手机": 3000, "平板": 2000, "相机": 1500 } # 字符串与列表操作 # 输出产品名称并连接成字符串 product_names = list(sales_data_A.keys()) product_names_str = ", ".join(product_names) print("产品名称：", product_names_str) # 判断手机是否在列表中 is_phone_in_list = "手机" in product_names print("手机是否在列表中：", is_phone_in_list) # 数值运算 # 计算每种产品周销量 weekly_sales = {} for product, sales in sales_data_A.items(): weekly_sales[product] = sum(sales) print("每种产品周销量：", weekly_sales) # 找出周销量最大的产品 max_weekly_sales_product = max(weekly_sales, key=weekly_sales.get) print("周销量最大的产品：", max_weekly_sales_product) # 字典操作 # 计算每种产品销售额 sales_amount = {} for product, sales in sales_data_A.items(): sales_amount[product] = sum(sales) * prices[product] print("每种产品销售额：", sales_amount) # 找出销售额最大的产品 max_sales_amount_product = max(sales_amount, key=sales_amount.get) print("销售额最大的产品：", max_sales_amount_product) # 列表加循环 # 计算每日总销量 daily_total_sales = [] for i in range(7): daily_total = 0 for sales in sales_data_A.values(): daily_total += sales[i] daily_total_sales.append(daily_total) # 找出最大日销总量对应的日期 max_daily_total = max(daily_total_sales) max_daily_total_index = daily_total_sales.index(max_daily_total) days = ["周一", "周二", "周三", "周四", "周五", "周六", "周日"] print("最大日销总量对应的日期：", days[max_daily_total_index]) # 集合(set)操作 # 两店共同销售品项 products_A = set(sales_data_A.keys()) products_B = set(sales_data_B.keys()) common_products = products_A.intersection(products_B) print("两店共同销售品项：", common_products) # A 店独有品项 unique_products_A = products_A.difference(products_B) print("A 店独有品项：", unique_products_A) # 全部品项 all_products = products_A.union(products_B) print("全部品项：", all_products) ```
