Python hasattr() Function Example 1

The below example shows the working of hasattr().

class Employee:
    age = 21
    name = 'Phill'

employee = Employee()

print('Employee has age?:', hasattr(employee, 'age'))
print('Employee has salary?:', hasattr(employee, 'salary'))

Output:

Employee has age?: True
Employee has salary?: False

Explanation: In the above example, we have created a class named as Employee, then we create the object of the Employee class, i.e., employee. The hasattr(employee, 'age') returns the true value as the employee object contains the age named attribute, while hasattr(employee, 'salary')) returns false value as the employee object does not contain the salary named attribute.
