快递计费编程可以根据不同的需求和规则来实现。以下是几种常见的实现方法:
方法一:基本重量计费
```python
def calculate_shipping_cost(weight):
假设每公斤5元运输费
cost = weight * 5
return cost
示例
weight = float(input("请输入重量(kg): "))
cost = calculate_shipping_cost(weight)
print(f"您好,此件包裹价格为: {cost}元")
```
方法二:分段计费
```python
def calculate_shipping_cost(weight, area_code):
if weight <= 5:
cost = weight * 3
elif 5 < weight <= 10:
cost = 5 * 3 + (weight - 5) * 3.5
elif 10 < weight <= 20:
cost = 5 * 3 + 5 * 3.5 + (weight - 10) * 4
elif 20 < weight <= 30:
cost = 5 * 3 + 5 * 3.5 + 10 * 4 + (weight - 20) * 4.5
elif 30 < weight <= 50:
cost = 5 * 3 + 5 * 3.5 + 10 * 4 + 20 * 4.5 + (weight - 40) * 5
else:
cost = "这么重,寄个鸡儿?"
return cost
示例
weight = float(input("请输入重量(kg): "))
area_code = input("请输入地区编号(01.华东地区 02.华南地区 03.华北地区): ")
cost = calculate_shipping_cost(weight, area_code)
print(f"您好,此件包裹价格为: {cost}元")
```
方法三:考虑体积重量
```python
def calculate_shipping_cost(weight, volume):
假设体积重量计算公式为: 体积重量 = 长(cm) × 宽(cm) × 高(cm) / 5000(cm³)
volume_weight = (length * width * height) / 5000
if weight > volume_weight:
actual_weight = weight
else:
actual_weight = volume_weight
假设运费计算公式为: 实重货: 运费 = (首重运费 + (重量(公斤) × 2 - 1) × 续重运费) + 总燃油附加费
if actual_weight <= 10:
cost = 20 + (actual_weight - 1) * 3
else:
cost = 20 + 10 * 3 + (actual_weight - 10) * 4
return cost
示例
length = float(input("请输入长度(cm): "))
width = float(input("请输入宽度(cm): "))
height = float(input("请输入高度(cm): "))
weight = float(input("请输入重量(kg): "))
cost = calculate_shipping_cost(weight, volume_weight)
print(f"您好,此件包裹价格为: {cost}元")
```
方法四:复杂计费规则
```python
def calculate_shipping_cost(weight, area_code):
if area_code == "01":
if weight <= 1:
cost = 15
else:
cost = 13 + 2 * (weight - 1)
elif area_code == "02":
if weight <= 1:
cost = 12
else:
cost = 12 + 2 * (weight - 1)
elif area_code == "03":
if weight <= 1:
cost = 14
else:
cost = 14 + 4 * (weight - 1)
else:
cost = "Error in Area"
return cost
示例
weight = float(input("请输入重量(kg): "))
area_code = input("请输入地区编号(01.华东地区 02.华南地区 03.华北地区): ")
cost = calculate_shipping_cost(weight, area_code)
print(f"您好,此件包裹价格为: {cost}元")
```
