5.5 Mutability and Immutability
In Python, objects are either mutable or immutable. Mutable objects can be changed after they are created, while immutable objects cannot. Knowing the mutability of the data structure you are working with is crucial as it can affect the way you manipulate data.
For example, with mutable objects, you can add or remove elements from a list, while with immutable objects, you must create a new object if you want to make any changes. This means that if you are working with a large dataset, understanding the mutability of the objects you are using can have a significant impact on the performance of your code.
Knowing the mutability of an object can help you avoid unexpected bugs or errors in your code, as you can better predict how the object will behave when you manipulate it. Therefore, it is important to always consider the mutability of objects when working with Python, and to use this knowledge to write more efficient, robust, and bug-free code.
