如何高效生成快递单打印源码？

class ExpressOrder:
    def __init__(self, sender_name, sender_address, receiver_name, receiver_address, package_weight):
        self.sender_name = sender_name
        self.sender_address = sender_address
        self.receiver_name = receiver_name
        self.receiver_address = receiver_address
        self.package_weight = package_weight
    def print_order(self):
        print("寄件人姓名：", self.sender_name)
        print("寄件人地址：", self.sender_address)
        print("收件人姓名：", self.receiver_name)
        print("收件人地址：", self.receiver_address)
        print("包裹重量：", self.package_weight, "kg")
if __name__ == "__main__":
    order = ExpressOrder("张三", "北京市朝阳区", "李四", "上海市浦东新区", 2.5)
    order.print_order()

这个源码定义了一个名为ExpressOrder的类，用于存储快递单的信息，类的构造函数接收寄件人和收件人的姓名、地址以及包裹的重量作为参数。print_order方法用于打印快递单的详细信息。

在主程序中，我们创建了一个ExpressOrder对象，并调用print_order方法来打印快递单信息。
