What is Python? — UK Software Development Guide
Direct Answer
Python is a high-level, general-purpose programming language known for its clear syntax and readability. Python is versatile — used for web development (Django, FastAPI), artificial intelligence and machine learning (TensorFlow, PyTorch, scikit-learn), data engineering (pandas, Apache Spark), automation, and scripting.
Python in the UK
Python is the dominant language for AI/ML development in the UK — and increasingly for backend web development. UK Python developer demand is highest in: FinTech (quantitative analytics, risk modelling), HealthTech (clinical data analysis, ML diagnostics), and eCommerce (demand forecasting, personalisation). Python AI/ML engineers command a 40–60% salary premium above standard developers in the UK. Django is used for complex web applications; FastAPI is growing for API-first microservices. Python developers are required to stay on supported versions — Python 3.9 reaches end-of-life October 2025.
