好的,我可以为您提供一个简单的 Python 购物平台代码,实现您所要求的功能。首先,我们需要定义一个商品类,包括商品名称、价格和数量:
```python
class Product:
def __init__(self, name, price, quantity):
self.name = name
self.price = price
self.quantity = quantity
```
接下来,我们需要定义一个购物车类,包括添加商品、查看购物车、修改商品数量、移除商品和清空购物车等功能:
```python
class ShoppingCart:
def __init__(self):
self.products = []
def add_product(self, product):
self.products.append(product)
def view_cart(self):
if not self.products:
print("Your shopping cart is empty.")
else:
for product in self.products:
print(f"{product.name} - ${product.price} x {product.quantity}")
def update_quantity(self, product_name, new_quantity):
for product in self.products:
if product.name == product_name:
product.quantity = new_quantity
break
def remove_product(self, product_name):
for product in self.products:
if product.name == product_name:
self.products.remove(product)
break
def clear_cart(self):
self.products = []
```
最后,我们可以创建一些商品,并将它们添加到购物车中,然后执行一些操作:
```python
# Create some products
product1 = Product("iPhone 12", 999, 1)
product2 = Product("MacBook Pro", 1499, 1)
product3 = Product("AirPods Pro", 249, 2)
# Create a shopping cart
cart = ShoppingCart()
# Add products to the cart
cart.add_product(product1)
cart.add_product(product2)
cart.add_product(product3)
# View the cart
cart.view_cart()
# Update the quantity of a product
cart.update_quantity("AirPods Pro", 1)
# Remove a product from the cart
cart.remove_product("iPhone 12")
# Clear the cart
cart.clear_cart()
# View the cart again
cart.view_cart()
```
这个代码可以实现您所要求的所有功能。当然,您可以根据需要对其进行修改和扩展。
