使用add_bundle_to_order()将产品捆绑包和变体子项添加到订单/购物车

def check_inventory(variant_items):
    for item in variant_items:
        if item.stock < item.quantity:
            return False
    return True

def add_bundle_to_order(bundle, variant_items):
    if check_inventory(variant_items):
        # 添加订单逻辑
        pass
    else:
        print("库存不足，无法添加到订单")

def calculate_bundle_price(bundle, variant_items):
    total_price = 0
    for item in variant_items:
        total_price += item.price * item.quantity
    if bundle.discount:
        total_price *= (1 - bundle.discount)
    return total_price

def add_bundle_to_order(bundle, variant_items):
    total_price = calculate_bundle_price(bundle, variant_items)
    # 添加订单逻辑，包括总价
    pass
