Python is Changing – Here’s What’s Coming
The Python Developer Survey 2024 reveals key trends shaping Python's future. FastAPI is overtaking Flask and Django for API development, while data science usage has grown to 51% of developers. Popular tools include pandas and numpy for data analysis, PyTorch gaining ground over TensorFlow for ML, and new package managers like UV showing rapid adoption. Most Python developers have less than 2 years of professional experience, making expertise valuable. The survey highlights Python's continued dominance in web development, data science, and machine learning, with emerging tools like Streamlit for dashboards and Pydantic for validation becoming standard.

Python programming roadmap - what skills should you learn first
A structured 6-phase roadmap for learning Python programming effectively. Starts with core fundamentals (variables, data types, loops, functions), progresses through small projects and object-oriented programming, covers developer tools like Git and virtual environments, then specializes in one area (web dev, data analysis, automation, or AI). Advanced phases include Pythonic features like list comprehensions and decorators, plus performance concepts like threading and async programming. Emphasizes the 80/20 rule of spending 80% time coding and 20% learning theory.
