Python Development: What Is It and Why Do People Choose It?

Python is an interpreted, interactive, object-oriented programming language that is great for a wide range of tasks and has a very clean syntax. Originally developed in 1991 by a programmer named Guido van Rossum, Python is now one of the most used programming languages in the world.

 

Some key features that make Python a popular choice for development projects include:

 

Easy to Learn and Use

Python is easier to learn than other languages such as Java or C++ because it has an English like structure. Due to readability, the code written in Python is easy to understand and simple, and therefore, the developers can start coding as soon as possible.

 

Extensive Libraries and Frameworks

Python also has a rich set of open-source libraries and frameworks for jobs such as Web Development, Scientific Computing, Data Analysis, Machine Learning, and many more. Some of the most used are Django, Flask, NumPy, Pandas, TensorFlow, PyTorch, and several more. This rich environment allows for the quick creation of applications.

 

Cross-Platform Compatibility

Python code can be executed on multiple operating systems including Windows, macOS, and Linux, without the need for modification. This cross-platform compatibility enables Python developers to code an application once and make it run on different platforms. This is a huge advantage if you want to outsource Python development services, as it allows you to save a lot of money.

 

Supports Multiple Programming Paradigms

Python supports a number of programming paradigms, including object-oriented, procedural, and functional programming paradigms. This flexibility enables developers to use the approach that best suits their project and to incorporate the paradigms where necessary.

 

Interpreted Language

Unlike most computer languages, Python code does not require compilation before it can be run. This is because new code can be executed as soon as it is written, which makes for faster testing and debugging.

 

Dynamically Typed

Python is an example of a dynamically typed language; this means that the type of a variable is determined at runtime and not declared. This leads to quicker development and greater flexibility.

 

Open Source and Free

Python is open-source software that can be downloaded and used with no restrictions from the software's owners. This has helped spread it throughout industry and academia. This makes it easier for developers to inspect source code and make contributions since the platform is open.

Key Uses of Python

Statista says that Python is the second most used programming language because it can be applied in nearly any way possible.

Getting Started with Python Development

Interested in leveraging Python for your own projects? Here is a concise guide to help beginners start with Python:

Install Python

First, download and install the newest stable version of Python, currently 3.12.6. Python is usually pre-installed in Mac and Linux distributions. On Windows, download installers from Python’s official website. Verify installation by checking the Python version:

 

# python3 --version

Python 3.12.6

Set Up a Code Editor

To write the Python programs, you will need a code editor. Some of the most used free code editors good for Python are VS Code, Atom, Sublime Text, and PyCharm. These come with basic utilities such as debugging, linting, code completion, and version control system integration.

Learn Python Basics

First, it is necessary to refresh the basic concepts of Python programming language, such as data types, variables, control structures, functions, classes, exceptions, and modules, before starting development projects. DataCamp, Codecademy, and Sololearn are some of the best platforms that provide easy Python lessons for beginners.

Reinforce all the concepts with the help of coding exercises so that the basics are clear. The simple and clean syntax of the Python language makes it easier to ease new learners into the language.

 

Explore Development Tools

Depending on your application area, it is recommended to look into Python libraries and frameworks to use for development tasks rather than creating them from scratch. For example, Django and Flask are used to develop web applications. Pandas, NumPy, and Matplotlib, are the tools that support data analysis work.

 

Build Your Own Projects

Now that you have understood the basics and tools, start creating your own Python programs and products. Divide ideas into stages. For instance, one can first create a basic command-line script that accepts input to generate meaningful output. Gradually increase project difficulty to challenge the brain.

 

Join the Python Community

Python developers from around the world offer great knowledge-sharing platforms in the form of forums, meet-ups, conferences, and open-source projects. Membership provides an opportunity to get an idea of the work of other professionals, receive advice, and learn about new trends in the field.

 

Python 2 vs Python 3

When getting started with Python, new developers may come across resources labeled Python 2 and Python 3 causing confusion about key differences.

Python 3 represents the modern era of Python development today. Released in 2008, it introduced significant improvements and changes over the older Python 2 standard first released in 2000.

While Python 2 development has ceased since 2020, a lot of existing legacy systems still rely on Python 2. However, all new Python projects should utilize Python 3. Let's compare some notable distinctions:

Print Statement

The print statement from Python 2 was replaced by the print() function in Python 3.

 

# Python 2

print "Hello world!" 

 

# Python 3

print("Hello world!")

Division Operator

In Python 3, the / division operator does the true division with the output of the floating point. The / operator in Python 2 uses classic division, so this operation is a floor integer division.

 

# Python 3 true division

10 / 3 = 3.3333

 

# Python 2 floor division 

10 / 3 = 3

Text vs Binary Data

In Python 3, text and binary data representations are clearly separated using str and bytes data types, correspondingly. Python 2 has a less strict distinction between text and binary data.

 

# Python 3

string = 'Hello world' 

data = b'Hello world'

 

# Python 2

string = 'Hello world'

data = 'Hello world' 

Unicode Support

Python 3 adopts Unicode text handling using UTF-8 encoding by default. Python 2 uses ASCII text without built-in Unicode support.

Iterators and Range

In Python 3, the range() function returns an iterator instead of a list. Several builtins also now return iterable objects instead of lists.

Exceptions

Python 3 includes changes to the built-in exceptions and the structure of the exceptions hierarchy. User-defined exceptions should be derived from Exception, not StandardError.

Modern Features

Some of the new features of python 3 are keyword-only arguments, chained comparisons, annotated assignments, matrix multiplication operators, type hints, better namespace handling through asynchronous generators, async/await syntax, and many more.

Future of Python

What does the future hold for the further development of Python over the course of the next 5 years and beyond?
