Python Programming Questions (OOP):
Question 2:
i)
Write a complete class called GasPump to represent a gas pump. The class should have a constructor to set the amount of available gas supply (in litres) and the price of gas per litre. The class should include:
-An accessor and a mutator to set and get the gas price.
-An accessor to get the current amount of gas supply.
-A method to add fuel to the gas supply. Note that the maximum capacity of the pump is 5000 litres. If we try to add too much fuel, once the maximum capacity is reached, no more fuel can be added.
-A method that sells a specific amount of gas. This method should reduce the supply of available gas by the amount sold and return the total cost of the gas sold. If the supply of the available gas is less than the amount requested, then only the existing supply should be sold.
ii)
Using the class defined in part
(i), add a driver that will:
- Create an object called ‘shell’ of the class GasPump and initializes it to 3000 litres and 78.5 cents a litre.
-Asks the user how much gas he/she wants to buy.
-Sells this amount of gas from shell.
-Adds 500 litres of gas to shell.
-Displays the content of gas supply left in shell.
