Example 1:
A class course is created with attributes name, duration, price, rating. An instance of the class is created and now we delete the rating attribute using delattr() method. Finally, we check if the rating attribute is present or not. A try block is used to handle the keyError
Python3
class course: name = "data structures using c++" duration_months = 6 price = 20000 rating = 5# creating an object of courseprint(course.rating)# deleting the rating attribute from objectdelattr(course, 'rating')# checking if the rating attribute is there or nottry: print(course.rating)except Exception as e: print(e) |
5 type object 'course' has no attribute 'rating'
