Given a list, write a Python program to convert the given list into a tuple. Initialize List of Tuple. The tuples in python are very similar to lists. Lists and tuples are part of the group of sequence data types—in other words, lists and tuples store one or more objects or values in a specific order. Both of them have an optional parameter key that expects a function. They are two examples of sequence data types (see Sequence Types — list, tuple, range). With tuple.

Python tuple() method along with List Comprehension can be used to form a list of tuples. The list elements get converted to a tuple. It is called sequence unpacking.5. Writing code in comment? Still, there is a significant difference between them, and that difference is tuples are immutable. #creating a tuple. A tuple is created by placing all the items (elements) inside parentheses (), separated by commas. 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’) ”. Because some downstream code may be expecting to handle tuple and the current list has the values for that tuple. Above, we defined a variable called list_num which hold a list of numbers from 1 to 4.The list is surrounded by brackets []. List and Tuple in Python are the class of data structure. Looping over a tuple of tuples. To access values in tuple, use the square brackets for slicing along with the index or indices to obtain value available at that index.
