What are the different ways of changing attribute values of an object in Python?

When working with objects in Python, the ability to change attribute values dynamically is a fundamental aspect of programming. Whether it’s modifying the state of an object based on user input, manipulating data structures, or adapting to changing conditions, understanding the various ways to change attribute values is crucial. In this thread, we will explore the different methods available in Python for modifying the attribute values of an object.

1. Using direct assignment technique:

It is the simplest way of assigning a new value to an attribute and involves using the respective names of the attribute with the assignment operator (=).

2. Using setter methods:

Another common approach is to define setter methods for each attribute within the class, which provide a controlled way to modify the attribute values. These can also be useful when you want to assign user inputs as values.

3. Using dictionary access:

Another technique involves changing the attribute’s value by accessing the object’s dictionary directly. This method allows you to modify the attribute values dynamically using the attribute dictionary associated with the instance.

4. Using "setattr()" function:

The setattr() function provides a convenient way to change attribute values dynamically and takes three arguments: the instance, the attribute name as a string, and the new value.
