Definition

Python is a programming language that is widely used in web applications, software development, data science, and machine learning (ML). Developers use Python because it is efficient and easy to learn and can run on many different platforms. Python software is free to download, integrates well with all types of systems, and increases development speed.

What are the benefits of Python?

Benefits of Python include:

  • Developers can easily read and understand a Python program because it has basic, English-like syntax.
  • Python makes developers more productive because they can write a Python program using fewer lines of code compared to many other languages.
  • Python has a large standard library that contains reusable codes for almost any task. As a result, developers do not have to write code from scratch.
  • Developers can easily use Python with other popular programming languages such as Java, C, and C++.
  • The active Python community includes millions of supportive developers around the globe. If you face an issue, you can get quick support from the community.
  • Plenty of helpful resources are available on the internet if you want to learn Python. For example, you can easily find videos, tutorials, documentation, and developer guides.
  • Python is portable across different computer operating systems such as Windows, macOS, Linux, and Unix.

How is Python used?

The Python language has several use cases in application development, including the following examples:

Server-side web development

Server-side web development includes the complex backend functions that websites perform to display information to the user. For example, websites must interact with databases, talk to other websites, and protect data when sending it over the network.

Python is useful for writing server-side code because it offers many libraries that consist of prewritten code for complex backend functions. Developers also use a wide range of Python frameworks that provide all the necessary tools to build web applications faster and more easily. For example, developers can create the skeleton web application in seconds because they don’t need to write it from scratch. They can then test it using the framework’s testing tools, without depending on external testing tools.

Automation with Python scripts

A scripting language is a programming language that automates tasks that humans normally perform. Programmers widely use Python scripts to automate many day-to-day tasks such as the following:

  • Renaming a large number of files at once
  • Converting a file to another file type
  • Removing duplicate words in a text file
  • Performing basic mathematical operations
  • Sending email messages
  • Downloading content
  • Performing basic log analysis
  • Finding errors in multiple files

Data science and machine learning

Data science is extracting valuable knowledge from data, and machine learning (ML) teaches computers to automatically learn from the data and make accurate predictions. Data scientists use Python for data science tasks such as the following:

  • Fixing and removing incorrect data, which is known as data cleaning
  • Extracting and selecting various features of data
  • Data labeling, which is adding meaningful names for the data
  • Finding different statistics from data
  • Visualizing data by using charts and graphs such as line charts, bar graphs, histograms, and pie charts
Data scientists use Python ML libraries to train ML models and build classifiers that accurately classify data. People in different fields use Python-based classifiers to do classification tasks such as image, text, and network traffic classification; speech recognition; and facial recognition. Data scientists also use Python for deep learning, an advanced ML technique.

Software development

Software developers often use Python for different development tasks and software applications such as the following:

  • Keeping track of bugs in the software code
  • Automatically building the software
  • Handling software project management
  • Developing software prototypes
  • Developing desktop applications using Graphical User Interface (GUI) libraries
  • Developing simple text-based games to more complex video games

Software test automation

Software testing is the process of checking whether the actual results from the software match the expected results to ensure that the software is error-free.

  • Developers use Python unit test frameworks, such as Unittest, Robot, and PyUnit, to test the functions they write.
  • Software testers use Python to write test cases for various test scenarios. For example, they use it to test the user interface of a web application, multiple software components, and new features.

Developers can use several tools to automatically run test scripts. These tools are known as Continuous Integration/Continuous Deployment (CI/CD) tools. Software testers and developers use CI/CD tools such as Travis CI and Jenkins to automate tests. The CI/CD tool automatically runs the Python test scripts and reports the test results whenever developers introduce new code changes.

What is the history of Python?

Guido Van Rossum, a computer programmer in the Netherlands, created Python. He started it in 1989 at Centrum Wiskunde & Informatica (CWI), initially as a hobby project to stay busy during Christmastime. The name for the language was inspired by the BBC TV show Monty Python’s Flying Circus because Guido Van Rossum was a big fan of the show.

History of Python releases

  • Guido Van Rossum published the first version of the Python code (version 0.9.0) in 1991. It already included good features such as some data types and functions for error handling.
  • Python 1.0 was released in 1994 with new functions to easily process a list of data, such as map, filter, and reduce.
  • Python 2.0 was released on October 16, 2000, with new useful features for programmers, such as support for Unicode characters and a shorter way to loop through a list.
  • On December 3, 2008, Python 3.0 was released. It included features such as the print function and more support for number division and error handling.

What are the features of Python?

Following features of the Python programming language make it unique:

An interpreted language

Python is an interpreted language, which means it directly runs the code line by line. If there are errors in the program code, it will stop running. Therefore, programmers can quickly find errors in the code.

An easy-to-use language

Python uses English-like words. Unlike other programming languages, Python doesn’t use curly brackets. Instead, it uses indentation.

A dynamically typed language

Programmers do not have to declare variable types when writing code because Python determines them at runtime. Because of this, you can write Python programs more quickly.

A high-level language

Python is closer to human languages than some other programming languages. Therefore, programmers do not have to worry about its underlying functionalities such as architecture and memory management.

An object-oriented language

Python considers everything to be an object, but it also supports other types of programming such as structured and functional programming.

What are Python libraries?

A library is a collection of frequently used codes that developers can include in their Python programs to avoid writing code from scratch. By default, Python comes with the Standard Library, which contains a lot of reusable functions. In addition, more than 137,000 Python libraries are available for various applications, including web development, data science, and machine learning (ML).

Matplotlib

Developers use Matplotlib to plot data in high-quality two- and three-dimensional (2D and 3D) graphics. It is often used in scientific applications. With Matplotlib, you can visualize data by displaying it in different charts such as bar charts and line charts. You can also plot multiple charts at once, and the graphics are portable across all platforms.

Pandas

Pandas provides optimized and flexible data structures that you can use to manipulate time-series data and structured data, such as tables and arrays. For example, you can use Pandas to read, write, merge, filter, and group data. Many people use it for data science, data analysis, and ML tasks.

NumPy

NumPy is a popular library that developers use to easily create and manage arrays, manipulate logical shapes, and perform linear algebra operations. NumPy supports integration with many languages such as C and C++.

Requests

The Requests library provides useful functions that are required for web development. You can use it to send HTTP requests, add headers, add URL parameters, add data, and perform many more tasks when communicating with web applications.

OpenCV-Python

OpenCV-Python is a library that developers use to process images for computer vision applications. It provides many functions for image processing tasks such as reading and writing images simultaneously, building a 3D environment from a 2D one, and capturing and analyzing images from video.

Keras

Keras is Python’s deep neural network library with excellent support for data processing, visualization and much more. Keras supports many neural networks. It has a modular structure that offers flexibility in writing innovation applications.

What are Python frameworks?

A Python framework is a collection of packages and modules. A module is a set of related code, and a package is a set of modules. Developers can use Python frameworks to build Python applications more quickly because they do not have to worry about low-level details such as how communications happen in the web application or how Python will make the program faster. Python has two types of frameworks:

  • A full-stack framework includes almost everything that is required to build a large application.
  • A microframework is a basic framework that provides minimal functionalities for building simple Python applications. It also provides extensions if applications need more sophisticated functions.

Developers can use multiple Python frameworks to make their development efficient, including the following frameworks:
