Python®
the language of today and tomorrow
Python is the gift that keeps on giving. The more you understand Python, the more you can do in the 21st Century. As simple as that.
What
Python is a high-level, interpreted programming language known for its simplicity, readability, and versatility. It’s used everywhere – from web apps and automation tools to data science and artificial intelligence. Whether you’re streaming a show, booking a flight, or chatting with an AI, Python is likely working behind the scenes.
Who
Python was created by Guido van Rossum and first released on February 20, 1991. While the word "python" might bring to mind a large snake, the language’s name actually comes from the classic BBC comedy series Monty Python’s Flying Circus.
What makes Python unique is that it began as the vision and work of a single person. Unlike most languages born in big tech companies, Python was created by Guido – driven by a simple goal: to make programming more intuitive and enjoyable.
From that idea, a global community has grown. Thousands of developers, educators, scientists, and enthusiasts continue to shape Python, expanding its reach into AI, data science, education, and beyond.
Today, Python is maintained and advanced by the Python Software Foundation (PSF), a non-profit organization dedicated to supporting the language, its ecosystem, and the global community that keeps it thriving.
Why
Python is everywhere – from websites and mobile apps to AI assistants, satellites, and even medical devices. It’s one of the most widely used programming languages in the world, with billions of lines of code written, shared, and reused every day. Behind this success is a vibrant global community that makes learning and collaboration easy for everyone, from absolute beginners to AI researchers.
Python is also one of the best languages to start learning programming. Here’s why:
- It's easy to learn – its clear and readable syntax helps you focus on problem-solving, not on memorizing complex rules.
- It's fast to use – you can build and test ideas quickly, whether it’s a simple script or a full application.
- It's free and open – Python is open source and runs on any major platform – Windows, macOS, Linux, or even Raspberry Pi.
Learning Python opens doors to countless career paths – from data analysis and web development to machine learning and cybersecurity. It’s not just a language; it’s a key skill for thriving in a world shaped by technology. Even if you never become a professional programmer, understanding Python helps you automate tasks, analyze information, and think more logically – valuable abilities in any field.
Where
Python is one of the most versatile tools you can learn – it opens doors across nearly every industry. With solid Python skills, you can work in fields like software development, data analytics, machine learning, automation, web development, cybersecurity, or quality testing. But its reach goes far beyond IT.
Python is increasingly used in finance, healthcare, education, science, and even the arts. Educators use it to teach logic and problem-solving, economists use it to analyze markets, psychologists to study behavior, and designers to automate creative workflows. It’s also the language behind countless research projects, simulations, and AI-driven innovations shaping the modern world.
As technology becomes part of nearly every profession, Python stands out as a universal language – simple enough for beginners, yet powerful enough for experts. Whether you’re managing data, automating reports, or exploring new ideas, Python helps you do it faster, smarter, and more creatively.
How
Learn, certify, and succeed! Imagine writing your own apps, automating tasks, or even creating an AI-powered project – all with Python. It’s a versatile, multi-paradigm language trusted by innovators and global companies like Google, Meta, Cisco, and Netflix. With its clear, human-friendly syntax, Python is the perfect first language to learn and a powerful skill to master.
Start your journey with the Python Essentials 1 course and prepare for the PCEP™ certification exam. Once you’ve learned the fundamentals, continue with Python Essentials 2 and prepare for the PCAP™ certification exam to deepen your programming skills.
If you’re ready to take your expertise even further, explore the professional-level courses and specialization paths that prepare you for PCPP, PCAD, PCAT, PCAA, and PCAS certifications – your next step toward becoming an advanced, industry-ready Python professional.
Python goals
Back in 1999, Guido van Rossum – the creator of Python – outlined a simple yet visionary set of goals for his language. He wanted Python to be:
- Easy and intuitive – approachable for beginners, yet powerful enough for professional developers.
- Open source – a community-driven project that anyone could improve and share.
- Readable and elegant – code that looks and feels almost like plain English, emphasizing clarity over complexity.
- Practical and efficient – designed for everyday tasks and fast development, enabling programmers to focus on solving problems rather than fighting syntax.
More than two decades later, those goals have not only been achieved but surpassed. Python has become the common language of innovation – powering everything from artificial intelligence and data science to web development, robotics, cybersecurity, and automation. It’s used at NASA to analyze mission data, at Netflix to recommend what you’ll watch next, and at OpenAI to train intelligent models.
Depending on which source you check, Python now ranks at or near the top of every major programming language index – consistently holding first place in both the TIOBE Programming Community Index and the PYPL Popularity of Programming Languages Index.
Python is no longer just a programming language – it’s a global standard for teaching, learning, and creating technology. Mature, reliable, and constantly evolving, Python continues to prove that simplicity and power can go hand in hand. Investing your time in learning Python isn’t just smart – it’s future-proof.

Python in Action
Where can we see Python in action? The short answer is: almost everywhere. From the apps on your phone to the systems that power global businesses, Python quietly runs behind the scenes, shaping how we search, shop, learn, and communicate online. It’s the language behind complex Internet services such as search engines, cloud computing platforms, and social media networks. Every time you stream music, get directions, or ask a chatbot a question – there’s a good chance Python is part of what makes it all work.
Python has become the go-to language for modern innovation. It powers artificial intelligence (AI) models, automates repetitive tasks, analyzes mountains of data, and supports the development of machine learning systems used in everything from voice assistants and image recognition to self-driving cars and recommendation engines. Whenever you interact with technologies like ChatGPT, Google Photos, or Netflix’s content suggestions, Python is working in the background.
Many of today’s developer tools and cloud platforms are built using Python. Scientists and researchers rely on it for data analysis, visualization, and simulation, while software testers use it to automate and repeat test procedures efficiently. Educators love it for its simplicity, and engineers appreciate it for its power and flexibility. The list keeps growing every year.
Python examples
Python is a great choice for:
- Artificial Intelligence and Machine Learning – building AI models, neural networks, and chatbots using TensorFlow, PyTorch, and scikit-learn.
- Data Science and Analytics – analyzing and visualizing data with pandas, NumPy, Matplotlib, and Seaborn.
- Web and Internet Development – powering websites and APIs with frameworks such as Django, Flask, and FastAPI.
- Automation and DevOps – writing scripts that automate workflows, manage servers, and deploy software efficiently.
- Education – introducing students to programming concepts through simple syntax and powerful tools like Jupyter Notebooks.
- Desktop and Mobile Apps – creating GUI applications with Kivy, PyQt, and wxPython.
- Game Development – powering games and simulations using Pygame or as part of major engines (e.g., the Battlefield series, Sid Meier’s Civilization IV).
- Business and Enterprise Solutions – driving ERP and e-commerce systems like Odoo and Tryton.
- Everyday Tools and Services – used by companies like Netflix, Uber, Dropbox, Pinterest, and Spotify for data processing, backend systems, and automation.
And that’s just the beginning – Python’s versatility and community support ensure that new and exciting uses appear every day.
