Comprehension to find the min in a dict

Question

I am curious about a thing:

I have a dict, for example with a car as key and a value regarding its speed. Now, I want to find the key with the lowest value.

Answer 1

How about this:

car_dict = {'mercedes': 200, 'fiat': 100, 'porsche': 300, 'rocketcar': 600}
min_car = {}
for car in car_dict:
    if not min_car or car_dict[car] < min_car['speed']:
        min_car['name'] = car
        min_car['speed'] = car_dict[car]
print(min_car)
