Python Core Programming: From Beginner to Real-World Development

This is a Python tutorial for beginners and those new to programming, structured as a progression from basic knowledge to core techniques to advanced applications to industry practice, in 16 chapters. The opening chapters begin with Python's origins, strengths and weaknesses, and application areas, then walk step by step through installing and running the interpreter on Windows, Linux, and macOS, and configuring and using PyCharm. They then cover basic syntax elements, operators and expressions, data types, built-in arithmetic functions, the three control structures (sequence, branch, loop), functions and parameter passing, recursion, and scope. The intermediate part covers composite data types such as lists, tuples, sets, and dictionaries; opening, reading, writing, and directory operations for files and file systems; regular expressions and the re module; processes and threads; and Python interfaces for relational, non-relational, and embedded databases. The web section introduces the Flask and Django frameworks, while the visualization section introduces NumPy and matplotlib and demonstrates cases such as hand-drawn-style images, polar plots, and stock candlestick charts. The final part explains GUI programming and layout management with PyQt 5 and then fully breaks down four comprehensive projects: a Pygame scoring game catching a bouncing ball, an intelligent poetry-writing program, a face recognition system, and a weather forecasting visualization system, covering requirements analysis, system design, implementation, and results. The code in the book is annotated, making it suitable for readers who want to ground syntax learning in a real development workflow.
