用python编辑从键盘上录入苹果的价格，重量， 输出：苹果单价9元斤，购买了5斤需要支付45元？

#苹果单价9元/斤，购买了5斤需要支付45元

def pay(x):

(Tab缩进)return 9*x#此处可改单价

if __name__ == "__main__":

(Tab缩进)ask=float(input("输入苹果重量(单位:斤):"))

(Tab缩进)print(f"购买了{ask}斤苹果，待付款:{pay(ask)}元")

fruits=["猕猴桃",125,"苹果",315,"香蕉",80,"草莓",50,"葡萄",70,"砂糖橘",200]

prices=[15,8,5,30,12,6]

all_listx=fruits+prices

for x in range(1,12,2):

if all_listx[x] <100:

print(all_listx[x-1])

望采纳
