Table 1
Instructions:
Part 1:
1. Create a project script with the following name “PetShop”.
2. Create python class, Cat with the appropriate attributes, constructor and method/s to represent the
task specification.
Part 2:
1. Create python class, CatMonitor to represent task specification.
2. Write python code to declare the appropriate data structure to hold and represent the following:
a.
b.
c.
d.
Cat ID and Cat Name
Cat ID and Age
Series of Age
Series of Cat id
3. Write python code to add appropriate attributes and methods signature to hold and manage the

information
a)
b)
c)
d)
cat id
cat name
average age
oldest age
Part 4:
1. Write python code to instantiate object from the class.
2. Write python code to use the instantiated object to retrieve and display average age:
Total average age – 3.8
3. Write python code to call instantiated object to retrieve and display cat id, cat name and age for the
oldest cat as follows:
Cat id : C5
Cat Name : Tammy
Age : 4
Part 5:
1. Write python code to call the instantiated object to prompt user to enter the following new cat id,
cat name and age as follows:
Cat id = C6
Cat Name = MooMoo
Age = 3
2. Write python code to call the instantiated object to retrieve and display the new average age
follows:
Total average age = 3.67
