Very basic Python confusion. How to take input from a multiple input and start array?-CodePudding

Hi this is a beginner code I wrote.

n = int(input())
for i in range(n):
    car, price = list(input().split())

#wanted to create cars into an array, but wrong code
for i in range(n):
    print(car[i], end = " ")`

Hi, this is a very basic doubt. I want to input the car and price in 1 line. Eg.

Audi 2
BMW 3
Ford 4

This is possible by

 for i in range(n):
    car, price = list(input().split())

But afterwards I want to group the cars and prices itself like

car = [Audi, BMW, Ford...]
prices = [2, 3, 4]

for i in range(n):
    print(car[i], end = " ").

My understanding of this line is wrong. Please correct and kindly restructure the code to the requirement.

CodePudding user response：

You have to collect the cars and prices in lists. Initialize the lists before the loop, then add cars and prices in the loop:

n = int(input())
cars = []
prices = []
for i in range(n):
    car, price = input().split()
    cars.append(car)
    prices.append(int(price))  # convert to number

However, a better idea might be to use a dictionary, to associate cars with their prices.

n = int(input())
cars_prices = {}
for i in range(n):
    car, price = input().split()
    cars_prices[car] = int(price)

This way, you can easily get the min, max, or sorted cars by price, e.g. cheapest = min(cars_prices, key=cars_prices.get).
