写了一段代码，请师兄师姐帮看下，给些建议或更简单的方法

建议：

1. 可以将地点编号和地点名称放在一个字典中，避免使用多个变量；
2. 在输入重量时可以加上输入提示，更加友好；
3. 可以将重量和运费计算部分提取出来，写成一个函数，避免代码重复。

改进后的代码如下：

locations = {1001: '东三省 / 宁夏 / 青海 / 海南', 1002: '新疆 / 西藏', 1111: '非偏远地区'}

def calculate_fee(weight, location): if location == 1001: if weight <= 3: return weight * 12 else: return 36 + (weight - 3) * 10 elif location == 1002: if weight <= 3: return weight * 20 else: return 60 + (weight - 3) * 20 elif location == 1111: if weight <= 3: return weight * 10 else: return 30 + (weight - 3) * 5 else: return None

location = int(input("请输入地点编号: ")) if location in locations: weight = float(input("请输入快递重量（公斤）: ")) fee = calculate_fee(weight, location) if fee is not None: print("发往：", locations[location], "，运费：", fee, "元！") else: print("不接受寄件！") else: print("不接受寄件！")
