Update Properties of Class Objects in Python

Update Properties of Class Objects

We can update properties of a class object using dot operator. Get the reference to the property of class object using dot operator . and assign a new value to this property using Assignment Operator =.

For example, if object1 is a class object in Python, then to update its property property1, with value value1, use the following syntax.

object1.property1 = value1


Let us take an example scenario where we have a class named Person with two properties: name, age.

We create an object person1 of type Person, with some initial values for its properties: Person('Mike', 22).

Then, we shall update the property age using the above specified syntax.

Python Program

class Person:
    def __init__(self, name="NA", age="0"):
        self.name = name
        self.age = age

    def printDetails(self):
        print("Person Details")
        print("Name :", self.name)
        print("Age  :", self.age)

person1 = Person("Mike", 22)

# For some reason we need to update age
person1.age = 35

Run Code Copy


Person Details
Name : Mike
Age  : 35
