Difference between Tuple and List in Python at TCCI

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.

·         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.

·         Inside Storage

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

o   Lists in a Tuple

• Likewise, we can also use a tuple to store lists. Let’s see how.

·         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.

o   >>> person=('ABC','admin','12345')

• But when you want to store similar elements, like in an array in C++, you should use a list.

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