Car rental, python have more than one car available

Thanks to the response of @ aeportugal, I have solved the inconvenience of checking if a car is available again to rent, now to do it with 2 or more cars, the level of complexity goes up.

This application simulates a system for renting vehicles, each day a customer can rent x amount of vehicles (this value is given by a #alternative), followed by a variable available that looks at the amount of cars available to rent (to have more cars than available vehicles, a fine is charged). If there are available vehicles, another #random will run to know how many days you will use them. and the rental price is calculated and totaled.

In the code is the Auto class, where the car is initialized and the rent price by the constructor. followed by three methods:
sumar_ganancia > is encartga of adding the profit that obtained every day.
subtract_dia_to_delete > subtract the days I rent the car to 0, to make the car available again.
verify_availability > check if there is a car available to use.
the output of this program is as follows.

The code is this;

I am trying to do it with more than one car available, I still have problems. Does anyone have any idea how to do it?
