Lists and Tuples

Posted On February 1, 2023

In Python, both lists and tuples are used to store collections of items. They are similar in many ways, but they have some key differences.

A list is a mutable, ordered sequence of elements. Lists are defined using square brackets ([]), and the elements of a list are separated by commas. For example:

my_list = [1, 2, 3, 4]

You can access, add, remove and update elements in the list using the indexing and slicing.

#Access an element
print(my_list[2])  #Output 3

#Add an element
my_list.append(5)

#remove an element
my_list.remove(3)

A tuple is an immutable, ordered sequence of elements. Tuples are defined using parentheses (()), and the elements of a tuple are separated by commas. For example:

my_tuple = (1, 2, 3, 4)

You can access the element of the tuple using indexing and slicing but you cannot change the element once it is created.

In general, lists are more flexible than tuples because they can be modified, but tuples can be used in situations where data immutability is required.

Also, Lists are more memory consuming than tuple due to the ability to change its elements.
