Design philosophy
Python's guiding principle: code should be readable. Indented blocks, English-like syntax, batteries-included standard library. The Zen of Python: Explicit is better than implicit. Simple is better than complex.
Interpreted and dynamic
Python is interpreted — no build step. Variables are dynamically typed. This makes Python fast to write but slower to execute than compiled languages like Go or Rust.
The AI ecosystem
Python dominates AI. NumPy and SciPy for numerics, Pandas for data frames, PyTorch and TensorFlow for deep learning, Hugging Face Transformers for LLMs. The entire AI toolchain is Python-first.
Web development
Django: full-featured opinionated framework. Flask: minimal. FastAPI: modern async APIs with automatic OpenAPI docs. FastAPI is the default for backend AI services.
Python 3
Python 2 reached end-of-life January 2020. All modern Python targets Python 3 (currently 3.12–3.13). High-throughput research services leverage modern async patterns in Python 3.
