5 PM – Python OOP – Bill

Today We:

1. Reviewed HW and attributes of a class that have a default value
2. Added a gas_tank attribute that also has a default value
3. Made a fill_gas_tank method
4. Added a drive method that lets the car use up gas
5. Created a new empty list variable called garage
6. Filled the garage list with a bunch of car instances
7. Looped through each car in the garage and printed them out
8. Learned how to only print out a car that meets specific criteria like printing out only toyota cars

Your HW:

1. Open your restaurant class hw
2. Do Page 167 – TRY IT YOURSELF
3. Download and install latest Python from: https://www.python.org/downloads/
4. Download and install latest Community Edition Pycharm: https://www.jetbrains.com/pycharm/download/
5. Optional Practice On the Car Class:
   • Make a max_gas_tank atribute that needs to be in the __init__ function
   • Make it so the gas_tank default atribute cannot be greater than the max_gas_tank attribute in the fill_gas_tank method
   • Create another new atribute, miles_per_gallon, that also needs to be in the __init__ function
   • Make it so in the drive method, instead of dividing the distance by 50 for the gas_consumption variable, divide the distance by the miles_per_gallon attribute.
   • Make sure that anytime you created a new car to specify the new max_gas_tank attribute and the miles_per_gallon attribute.
