The use of lists and dictionaries in Python programming

Sample Answer

In Python, lists and dictionaries are two of the most fundamental and versatile data structures used to store and manage collections of data. While both can hold multiple values, they differ significantly in how they organize and access that data.

Python Lists

A list is an ordered and mutable collection of items. Think of it as a dynamic, resizable array.

Key Characteristics:

Ordered: The elements in a list have a defined order, and you can access them by their index (position), which starts at 0.

Mutable: You can change, add, or remove elements from a list after it has been created.

Heterogeneous: A single list can contain elements of different data types, such as integers, strings, floats, and even other lists.

Use Case:

Lists are ideal for storing a sequence of items where the order matters and you need to access elements by their position. Examples include a list of names, a sequence of numbers, or a series of tasks.
