1. Write a class called Bicycle, which contains two attributes, gear, which describes the type of gear the bicycle has, and speed, the max speed the bicycle can reach. 2. Write a class called MountainBike which inherits Bicycle and has one extra attribute, which is the seatHeight. 3. Write a main function in which define an object of type MountainBike that has a manual gear, speed of 20, and seat height of 10. Then print the object status. Notes: • All attributes in class Bicycle and class MountainBike are private. • Both classes have method_str_, which returns a string that represent the object. Method _str_ in class MountainBike calls method_str_from class Bicycle and then concatenates the value of seatHeight (same as when init in supclass calls _init_ from superclass). • No need to write getters and setter.

In Python:

1. Write a class called Bicycle, which contains two attributes, gear, which describes the type of gear the bicycle has, and speed, the max speed the bicycle can reach. 2. Write a class called MountainBike which inherits Bicycle and has one extra attribute, which is the seatHeight. 3. Write a main function in which define an object of type MountainBike that has a manual gear, speed of 20, and seat height of 10. Then print the object status. Notes: • All attributes in class Bicycle and class MountainBike are private. • Both classes have method_str_, which returns a string that represent the object. Method _str_ in class MountainBike calls method str_ from class Bicycle and then concatenates the value of seatHeight (same as when init in supclass calls _init_ from superclass). • No need to write getters and setter.
