In this tutorial, we will learn how to initialize a list of tuples and some of the operations on this list of tuples. After writing the above code (Python convert list to a tuple), Ones you will print ” my_tuple ” then the output will appear as a “ (‘Tim’, ‘ John’, ‘Mark’) ”. The items in a list are separated by commas and enclosed in square braces. Approach #2 : Tuples are used to store multiple items in a single variable.
