Question

如果我有这个清单

car=['Mazda','ford','Honda','corvette','Mercedes']
price=['300','450','350','490','500']

我希望一次打印以下句子

print ("that", car,"car price is:",price ,"in thousands dollar")

如何编写条件我通常使用此但如何为列表执行此操作？

car=input("enter car name:")
price=float(input("price of the car:"))

因为它只会打印我在

中输入的值

car=input("enter car name:")
price=float(input("price of the car:"))

Answer 1

如何为列表执行此操作？

使用zip()功能：

cars = ['Mazda','ford','Honda','corvette','Mercedes']
prices = ['300','450','350','490','500']

for car, price in zip(cars, prices):
    print("that {} car price is: {} in thousands dollar".format(car, price))

输出：

that Mazda car price is: 300 in thousands dollar
that ford car price is: 450 in thousands dollar
that Honda car price is: 350 in thousands dollar
that corvette car price is: 490 in thousands dollar
that Mercedes car price is: 500 in thousands dollar

Answer 2

首先使用for循环：

car = ['Mazda', 'ford', 'Honda', 'corvette', 'Mercedes']
price = ['300', '450', '350', '490', '500']
for i in range(len(car)):
    print ("that", car[i],"car price is:",price[i] ,"in thousands dollar")

然后一个循环：

i = 0
while(i < len(car)):
    print ("that", car[i],"car price is:",price[i] ,"in thousands dollar")
    i += 1

Answer 3

你可以压缩这两个列表，但是我认为字典是这个任务的正确数据结构。

car_prices = {
'Mazda': 300,
'Ford': 450,
'Honda': 350,
'Corvette': 490,
'Mercedes': 500
}

for car, price in car_prices.items():
 print("that {} car price is: {} in thousands dollar".format(car,price))
