 Python Data Structures

What is Python?

Python is an object-oriented language that most developers use. Most professionals who are entering the field prefer to use Python due to its versatility, simplicity, and community support. Individuals can start learning and practicing coding with Python. It has a large number of libraries that make it easy to use. 

It is an interpreted, high-level, and dynamic language that has built-in data structures, dynamic typing, and dynamic binding. Thus, making it ideal for rapid application development. It can also be used as a scripting language for connecting existing components. Due to its easy-to-learn and concise syntax, Python prioritizes readability and lowers the cost of software maintenance. Python supports modules and packages that foster program modularity and allow the reuse of code. Another great feature of Python is its interpreter and standard library, as it is free to download.

Python is popular among programmers because of the enhanced productivity it offers. The edit-test-debug cycle is extraordinarily rapid because there is no compilation step. In Python, a bug input will never result in a segmentation fault because the scripts are easy to debug. If the interpreter finds a mistake, it throws an exception. If the interpreter fails to catch the exception, it prints a stack trace. 

Why Python?

There are multiple reasons for Python being the best option. It is one of the most popular programming languages and is easy to use. It also supports machine learning applications and is fast when compared to several other languages. The syntax is easier to understand, and pre-existing libraries minimize the need to code every piece of logic from scratch.

Python is a fast compiler, and because it is java-based, programmers can use it for more than analytical research, analytical modeling, and statistical modeling. Python-based web apps can be directly linked to the analytical models running in the background.

It can be easily combined with other programming languages or platforms, thus allowing IT analysts, programmers, and developers to transfer to the analytics domain. This is possible due to the common object-oriented design of Python. 

It also offers strong documentation support due to its coding style. As a result, the following points outline why we should use Python:

• Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.)
• Python has a simple syntax similar to the English language
• Compared to other languages, Python code can be written in fewer lines
• Prototyping can be done quickly in Python because it runs on an interpreter system that allows code to be executed as soon as it is written
• Python can be treated in a functional or object-oriented manner

Types of Data Structures in Python

Data Structures are built-in to Python and allow you to store and access data. List, Dictionary, Tuple, and Set are the names of these structures.

Users have complete control over the functionality as they can construct their data structures in Python. Some of the common data structures are Queue, Stack, Tree, and Linked List. 

1. Lists in Python

Lists are used to store data types such as text, integer, and other lists as well. Thus, they are one of the most flexible data structures in Python. 

2. Tuples in Python

Tuples are another common Python built-in data structure. These are very similar to Lists, with the exception that they are immutable. This means that no value can be added, deleted, or modified after a tuple is created.

3. Dictionary in Python

Another Python data structure for storing immutable but unordered heterogeneous things is the dictionary. This means that when you try to access the elements, they may not appear in the same sequence as when you first put them.

The way elements are stored in dictionaries, however, distinguishes them from lists. In a dictionary, we access elements by key values rather than index, as we did in a list. As a result, dictionaries include key-value pairs rather than single entries.

4. Sets in Python

Multiple instances of the same element in your list or tuple aren't always desirable. You can use a predefined data structure here. A set is a changeable, unordered collection of elements with unique values.
