商品单价99.80元，优惠价91.80元，返现150.00元，运费15.00元，输入购买商品数量，计算并输出购买商品的总金额、运费、返现金额、折扣率、商品优惠金额、实付总额。Python

在Python中，你可以创建一个函数来计算这个购物车的总金额。这里是一个简单的示例：

def calculate_total(item_count, unit_price, discount_price, refund, shipping):
    # 计算商品原价总金额
    total_price = item_count * unit_price
    
    # 计算商品优惠金额
    savings = item_count * (unit_price - discount_price)
    
    # 计算实际支付的金额
    after_discount = total_price - savings
    
    # 折扣率（假设是基于原价）
    discount_rate = (total_price - after_discount) / total_price if total_price != 0 else 0

    # 实付总额
    net_amount = after_discount + shipping - refund
    
    return {
        '总金额': total_price,
        '运费': shipping,
        '返现金额': refund,
        '折扣率': discount_rate,
        '商品优惠金额': savings,
        '实付总额': net_amount
    }

# 示例输入
item_count = int(input("请输入购买的商品数量："))
unit_price = 99.80
discount_price = 91.80
refund = 150.00
shipping = 15.00

result = calculate_total(item_count, unit_price, discount_price, refund, shipping)
for key, value in result.items():
    print(f"{key}: {value}")
