2. Python is a popular high-level programming language that is widely
used for various applications, from web development and data analysis
to artificial intelligence and scientific computing.
One of the key features of Python is its built-in support for various data
structures, which allows developers to efficiently store and manipulate
data in their programs.
In this explanation, we will discuss the main types of data structures in
Python and provide real-life examples of how they can be used.

Sequences: Sequences are data structures that store an ordered collection of items. Examples of
sequences in Python include lists, tuples, and strings.
Sets: Sets are data structures that store an unordered collection of unique items. Sets can be used
to efficiently remove duplicates from a list, perform set operations such as union and intersection,
and more.
Dictionaries: Dictionaries are data structures that store key-value pairs. They can be used to
efficiently look up values based on their keys, and to store data in a structured and organized way.
Stacks and Queues: Stacks and queues are data structures that store a collection of items in a
specific order. Stacks follow a “last-in, first-out” (LIFO) order, while queues follow a “first-in, first-
out” (FIFO) order.
Trees and Graphs: Trees and graphs are data structures that store hierarchical and interconnected
data. They can be used to represent complex relationships between data items, such as the
structure of a file system or a social network.

5. In conclusion, understanding data structures is an important aspect of Python
programming, as it can help developers write more efficient and effective code.
By knowing which data structure to use for a particular task, developers can
optimize their code for performance, readability, and maintainability.
We hope that this explanation has given you a good understanding of the main
types of data structures in Python and how they can be used in real-life
applications.
