print (2018)
else:
if 'color' in car:
print ('red')

Answer 1

Your code needs to take the key as input and output the corresponding value.

key = input()
Your data

if key == "brand":
print ('BMW')
else:
...

Answer 2

"brand" is a key in the car dictionary. To access the associated value we use car["brand"]. So it would be

if "brand" in car.keys():
print(car["brand"])

Answer 3

Your code will only print 'BMW' as it always evaluates to true coz the key " brand" exists in the dictionary 'car'.

If u are confused membership check for dictionary, then let me make it clear, the 'in' operator checks whether a key exists in a dictionary. brand, year, color, mileage are keys while BMW,2018, red, 15000 are values

Answer 5

So how do I correct it?? Kirabo Ibrahim

Answer 6

According to me you wanted you wanted to print the details of the car if it only existed in the dictionary but the existence is based on the 'brand' key.

Also u are using a dictionary to represent the car object and I will also assume you will have a collection of cars like this. [ {car_1}, {car_2}, ...{car_n} ]

Let me assume the above, then the code would be like:

brand = input()
cars =[{car_1}, ..., {car_n}]

for car in cars:
if car['brand'] == brand:
for k in car:
print(car[k])
