The object for which we are checking the attribute.

# This is constructor for python
def __init__(self, name, age):
self.name = name
self.age = age

# Teaching each cat how to meow
def meow(self):
print("I am a " + str(self.age) + " year old " + self.name)

# Creating an instance my_cat representing my cat Roxas
my_cat = Cat("Roxas", 26)
hasattr(my_cat, "age")
True

hasattr(my_cat, "height")
