tccicomputercoaching.com Definition • Tuple and List are used to store data in Python Language.

• Tuple: A tuple is a collection of values and it is declared using parentheses. However, we can also use a tuple packing to do the same, and unpacking to assign its values to a sequence.

• Lists: Unlike in C++, we don’t have arrays to work with in Python.

Here, we have a list instead.

tccicomputercoaching.com • Mutability – A List is Mutable – B Tuple is Immutable

• In built Methods: – Following Methos can apply to List append(), insert(), remove(), pop(), clear(), sort(), and reverse().

– But not applicable to Tuple.

tccicomputercoaching.com • Inside Storage – We can store tuples in a list when we want to. For example, – [(1, ‘ABC’), (2, ‘DEF’), (3, ‘GHI’)]

– Lists in a Tuple – Likewise, we can also use a tuple to store lists. Let’s see how.

tccicomputercoaching.com • Use: – >>> mytuple=([1,2],[3,4],[5,6]) – Use a tuple when you know what information goes in the container that it is.

For example, when you want to store a person’s

credentials for your website.

– >>> person=('ABC','admin','12345') But when you want to store similar elements, like in an array in C++, you should use a list.

– >>> groceries=['bread','butter','cheese']
