A class is like a blueprint and an instance is an object that we create using that blueprint. The properties of an instance are called instance variables and functions are called instance methods.
init method (also known as a class constructor in Python), which is executed right after an instance is created. When ClassName() is called and an instance is created, the init method will be called immediately after
class MenuItem:
def __init__(self):
print(' ') // call automatically
