A tuple is a sequence of immutable Python objects. A list in python is a collection of various items which may be either of the same or of different data types. Do not use this if the tuple may already be known to some other part of the code. In python, tuple is a collection of an ordered sequence of items to store the values of different data types. List and Tuple in Python are the class of data structure. This is a straight way of applying the tuple function directly on the list. By using our site, you Attention geek! We can apply the * operator we can expand the given list and put the result in a parentheses. Python Dictionary; Python Tuple; 1. They allow indexing or iterating through the list.

The difference between list and tuple is the mutability. The tuple is the same as List, but the only difference is the Tuples are immutable that means once you create the tuple object, you are not allowed to make any changes to the tuple object..
