![]() It simply means that you can change the existing values in a list. We have heard already that tuples are immutable while lists are mutable. In a tuple, changes and errors don't usually occur because of immutability. Inserting and deleting items is easier with a list.Īccessing the elements is best accomplished with a tuple data type.Ī tuple does not have many built-in methods because of immutabilityĪ unexpected change or error is more likely to occur in a list. Difference Between List and Tuple (Table)įollowing are the difference between list and tuple. So why would we use immutable data structures like tuples anyway? Well, one reason is that they have a small overhead compared to mutable data structures like lists and maps. They remain the same length throughout the lifecycle of the program. The reason is simple: tuples are immutable, meaning you cannot change their contents after they are created. But tuples? Well, you can't do any of that. You can add or remove items or reassign them to different variables. If you're familiar with lists and maps, you know that they can be modified. TypeError: 'tuple' object does not support item assignment Error message if you attempt to change one of the items: The contents of a tuple cannot change once they have been created in Python due to the immutability of tuples. The primary difference between tuples and lists is that tuples are immutable as opposed to lists which are mutable. Therefore, it is possible to change a list but not a tuple. Type(tuple_numbers) Difference Between List and Tuple in Python (An In-Depth Explanation) We can use the type function to check the data type of any object. ![]() Lists are surrounded by square brackets while tuples are surrounded by round brackets ( ). But there is a difference in its use cases and syntax as well. ![]() List and tuple act as containers for storing objects. Here’s an example of declaring a tuple in python. Here’s an example of declaring a list in python.Ī list can contain data of different data types. It also preserves the data sequence.Īs tuples are immutable, they are faster than the list because they are static. Tuples are used to store heterogeneous and homogeneous data.It comes in handy when storing a collection of items, especially if you want those items to be unchanging.Ī python tuple has the following features. Tuples are also a sequence data type containing elements of different data types. Because lists are dynamic, you can easily add or remove items anytime. Lists help store multiple items and then iterate over them using a loop. Lists help preserve data sequences and further process those sequences in other ways.You can use Python lists to store data of multiple types simultaneously.It is similar to an array in other languages like Java. Lists are one of the most flexible and powerful containers in Python.
