Day 4: Class vs. Instance.py

"""
Task
Write a Person class with an instance variable,age, and a constructor that takes an integer,initialAge, 
as a parameter. The constructor must assign initialAge to age after confirming the argument passed as initialAge
is not negative; if a negative argument is passed as nitialAge, the constructor should set age to 0 and print Age
is not valid, setting age to 0.. In addition, you must write the following instance methods:

  1. yearPasses() should increase the age instance variable by 1.
  2. amIOld() should perform the following conditional actions:
    - If age < 13, print You are young..
    - If age >= 13 and age < 18, print You are a teenager..
    - Otherwise, print You are old..
