Python is one of the most popular programming languages among developers because of its efficiency, flexibility, and ease of use. It is commonly used for developing websites, software, and more. It is also used in the field of data science and during AI training.
Python is considered a general-purpose programming language because it can be used for many different types of projects, as it is not specifically designed for any one application.
If you’re new to programming, this article provides a basic guide to help you understand what Python is, its advantages, and how to start using it.
Advantages of Python Compared to Other Programming Languages
Easy to Read, Learn, and Write
One of the reasons Python has become so popular is its simplicity. Its straightforward syntax makes it highly intuitive for developers, easy to interpret, and beginner-friendly.
But what makes Python so easy to learn? Its syntax is closer to human language compared to other programming languages. Languages with this characteristic are known as high-level programming languages.
Versatility
Python runs on nearly all system architectures and has a wide range of applications. It is also a cross-platform language, meaning it can be used on operating systems like Windows, macOS, Unix, and Linux without requiring code modifications, unlike languages like C.
Free and Open Source Nature
Anyone can use Python for free, even for commercial purposes. The latest version is available for download on Python’s official website.
Python being open source means that developers can modify the source code and create their own versions. This is useful for organizations that have to customize the language for specific needs.
Productivity
Python allows developers to write code faster and with fewer lines compared to other languages.
Additionally, Python has an extensive library of reusable code for various tasks, reducing the need to write code from scratch. There is also a large, active community of Python developers who provide support through forums and other platforms, making it easy to find solutions to problems online.
Compatibility
Python works well alongside other programming languages such as Java, C/C++, and SQL.
Career Opportunities
Python is one of the most in-demand programming languages in the job market. Many job listings for developers specifically request Python skills, and positions that require Python often come with competitive salaries.
Learning Python can open up many job opportunities, even for freelance developers. Python skills are not just for programmers—data analysts, product managers, and even computer science educators can benefit from knowing Python.
Limitations of Python
Despite being one of the most recommended programming languages, Python has some drawbacks.
Slower Performance: Python tends to be slower than other languages because it is dynamically typed and interpreted.
High Memory Usage: Python requires more memory than some alternatives, which can make it less suitable for certain applications. This is one of the reasons why Python is not commonly used for mobile app development.
Database Limitations: Python’s database interaction capabilities are less developed compared to other options like ODBC or JDBC.
Common Uses of Python
Software Development
Python is widely used for software development. This includes automating software testing to check performance and identify errors.
Automation
Python can be used for scripting, which allows computers to execute tasks without human intervention. It is often used to solve mathematical problems, check system errors, download content, and convert files.
Web Development
Python is commonly used for building the back end of websites and applications. The back end handles functions like data transfers, database communication, information processing, and security.
There are many Python frameworks available, such as Django and Pyramid, which provide a structured foundation for development.
Game Development
Since Python is easy to use, it’s great for creating simple games or prototypes. Even The Sims 4 was developed using Python. It is also a good choice for beginner game developers.
Data Analytics
Python plays a major role in data science and business intelligence. It is used to perform complex statistical calculations, manipulate and analyze data, develop machine learning algorithms, and create data visualizations.
How to Start Using Python
If you have no programming experience and want to learn Python, we recommend starting with the official Python tutorial. There are also many beginner-friendly tutorials online.
If you already have some programming knowledge, you might want to explore more advanced resources.
Companies That Use Python
Netflix
This streaming giant uses Python for a variety of tasks. It helps the platform automate security processes, assess risks, monitor data quality, and visualize information. Python also plays a key role in Netflix’s recommendation algorithm.
Google uses Python for back-end development and AI projects. YouTube, which is part of the Google ecosystem, is built with Python and relies on it for platform management, data analysis, and video administration.
Uber
Uber was originally built using Python and Node.js. Today, Python is primarily used for data processing within the company.
