A popular, general-purpose programming language known for readable syntax, widely used in AI, data science, automation, and web development.
Python was created by Guido van Rossum and first released in 1991. Its design emphasizes readability, using indentation to define code blocks, which makes it a common first language for beginners.
Python has a huge ecosystem of libraries. Data scientists use pandas and NumPy for analysis, machine learning engineers use scikit-learn and PyTorch, web developers use Django and Flask, and system administrators write automation scripts. For example, a few lines of Python can download a web page, extract all article titles, and save them to a spreadsheet. Python is generally slower than compiled languages like C++ for raw computation, but heavy work is often handled by optimized libraries written in faster languages underneath.
A reusable foundation of code, tools, and conventions that developers build applications on top of.
Jupyter NotebookAn open-source, browser-based environment that mixes live code, results, charts, and explanatory text in a single document.
Machine LearningA branch of AI in which computers learn patterns from data to make predictions or decisions without being explicitly programmed for each case.
