delattr() Function in Python

Python delattr() Function

The delattr() function in Python is used to delete an attribute from an object. It takes two arguments: the object from which the attribute is to be deleted, and the name of the attribute.

Here's the syntax for using the delattr() function:

delattr(object, attribute_name)

• object: This is the object from which the attribute will be deleted.
• attribute_name: This is a string representing the name of the attribute that will be deleted.

Here's an example that demonstrates the usage of delattr():

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

person = Person("Alice", 25)
print(person.name)  # Output: Alice

delattr(person, "name")
print(person.name)  # Raises an AttributeError: 'Person' object has no attribute 'name'

In the above example, we create a Person class with two attributes: name and age. We create an instance of the Person class called person and initially assign the name "Alice" to the name attribute. After calling delattr(person, "name"), the name attribute is deleted from the person object. When we try to access person.name again, it raises an AttributeError because the attribute no longer exists.

It's important to note that if the attribute doesn't exist in the object, delattr() will raise an AttributeError.
