Unlike lists, tuples are immutable. Code: Now, we are going to see different parameters differentiating Python tuples and lists. Python list is defined by square brackets. List and Tuple objects are sequences. List Code Snippet: A tuple is an assortment of data, separated by commas, which makes it similar to the Python list, but a tuple is fundamentally different in that a tuple is "immutable." Lists has more functionality than tuple. Lists has variable length, tuple has fixed length. We can create a list of tuples i.e. Pythontutorial.net helps you master Python programming from scratch fast. I've always heard that about lists and tuples, but this article made me wonder how much less efficient with storage is a list. List is like array, it can be used to store homogeneous as well as heterogeneous data type (It can store same data type as well as different data type). Since a named tuple is a regular Python class, it is easy to add or change functionality with a subclass. By membership, here we mean to find existence of element in a collection The focus of this post is to evaluate performance of list, tuple and set data structures with respect to each other … Continue reading Performance for testing memberships: list vs tuples vs sets → We cannot add an element to tuple but we can add element to list.
