完成地铁简易购票系统的Python代码 1.成人票5.0元一张 儿童票2.5元一张 2.输入购买成人票数量 输入购买儿童票数量 3.显示需要支付的金额

以下是地铁简易购票系统的 Python 代码，可以实现输入购买成人票数量和儿童票数量，计算需要支付的金额：

adult_price = 5.
child_price = 2.5

adult_num = int(input("请输入购买成人票数量："))
child_num = int(input("请输入购买儿童票数量："))

total_price = adult_num * adult_price + child_num * child_price

print("需要支付的金额为：", total_price, "元")
