Reading the value of the attribute of the object.

class Animal():

     #class attributes
    species='carnivores'

     #instance attributes
    def __init__(self1,name1,age):
        self1.name= name1
        self1.age=age
        

 #instantiate the Animal  class
tiger=Animal("Ronald",5) 

print(getattr(tiger,'age')) # 5
print(getattr(tiger,'species')) # carnivores 
print(hasattr(tiger,'age')) # True

In above code we collected the value of age attribute of tiger object.

Returning default value

Let us try to collect the value of one unknown attribute height by using the object.

print(tiger.height)

This line will generate error saying . AttributeError: 'Animal' object has no attribute 'height'
We can return default value of getattr() when the attribute is not found.

print(getattr(tiger,'height',' No such attribute '))

Output

 No such attribute
