How to delete Properties of an object in Python?

Summary: In this programming example, we will learn two different ways to delete properties of a user-defined object in Python.

Method 1: Using del

The del statement can easily delete a property of a Python object. For example, in the following code, we are deleting the department property of the Student object using the same.

class Student:
    def __init__(self, name, department):
        self.name = name
        self.department = department

        
obj = Student("Bicky Newton", "IT")
del obj.department  #deletes department property

Method 2: Using delattr()

The delattr() is an inbuilt method in Python that deletes the attribute (property) of the specified object.

Syntax:

delattr(obj, attribute)

Example:

class Student:
    def __init__(self, name, department):
        self.name = name
        self.department = department

        
obj = Student("Bicky Newton", "IT")
delattr(obj, department)  #deletes department property

These are the two methods using which we can delete the properties of a user-defined object in Python.
