Overview
What is Python?
Python is a high-level, general-purpose programming language created by Guido van Rossum and first released in 1991. Its defining trait is readability — Python code often reads close to plain English, using indentation instead of curly braces to define structure. This makes it one of the fastest languages for a beginner to pick up, while still being powerful enough to run some of the largest software systems in the world.
Why Python matters
Readable syntax
- fewer symbols, less boilerplate, code that looks like the logic it describes.
Batteries included
- a large standard library covers file handling, networking, math, and more without needing external tools.
Massive ecosystem
- third-party packages exist for almost anything — web frameworks (Django, FastAPI), data tools (pandas, NumPy), AI/ML (PyTorch, TensorFlow), and robotics (rclpy for ROS 2).
Cross-platform
- the same code runs on Windows, macOS, and Linux with little to no change.
Why Python matters in industry
Python is one of the top three most-used languages in the world today, and it’s the dominant language in several high-growth fields:
Data Science & AI/ML
nearly every major machine learning framework has Python as its primary interface.
Because it’s easy to learn but scales to serious production systems, Python is often the first language taught in universities and the first language reached for by professionals prototyping a new idea. This course starts from zero and builds toward writing real, working programs.
