3.1.1 List Definition and Access

A list is defined using square brackets and elements are separated by commas.
Each element in a list has a position called an index.

Defining a List

Lists can contain:

• Numbers
• Strings
• Other lists
• Mixed data types

Lists preserve the order in which elements are added.

Accessing List Elements

• List elements are accessed using their index
• Indexing starts at zero
• Negative indices access elements from the end

Accessing elements correctly is essential for data processing and iteration.

📌 Note:
Accessing an index outside the list range causes an error.
