This book is designed to take you on a journey through sophisticated concepts and techniques valuable not only in software engineering but across any domain where high-level Python proficiency is a critical asset. 🐍 Whether your work is in data science, academic research, or cloud infrastructure, the skills you acquire here will empower you to write more efficient, robust, and elegant code. ````{admonition} Who is this book for? :class: note This book is intended for those who are already comfortable with programming in general, but also with Python's fundamentals and object oriented programming. If you have a solid grasp of variables, control flow, functions, classes, and objects, you are ready to dive in! ```` ````{admonition} Important :class: important If you find this book useful, please give a star 🌟🌟🌟 to [the book's repo](https://github.com/HappyRavenLabs/python-beyond-basics). ```` ## About the Author ```{figure} ./figs/jwalczak.png --- scale: 20% align: right --- ``` My name is **Jakub Walczak**, and I am an academic and artificial intelligence researcher. My journey in education began in 2019 when I started my doctorate, which I completed in 2022 after graduating from Lodz University of Technology. Since then, I have had the pleasure of teaching students Python fundamentals and delivering advanced courses on machine learning and data science. Parallel to my academic career, I have been active in the industry since 2016. This practical experience has been invaluable and includes roles such as: * **Software Developer** at Comarch in Poland * **Scientific Software Developer** at the CMCC Foundation in Italy * **Cloud System Developer** for AI Operations at OpenNebula Systems This blend of academic theory and real-world application has shaped my approach to teaching and is the foundation upon which this book is built. ````{admonition} A Note from the Author :class: tip My goal is to help you move beyond basic Python knowledge and gain real control over your code. This book focuses on practical techniques, clever tricks, and deep insights that will transform how you approach development. These are the concepts that separate developers who *use* Python from those who truly *master* it. I hope this journey empowers you to write more elegant, efficient, and controlled code. Happy coding! ```` ## Prerequisites As this is a course to master Python, I need to make some assumptions about the knowledge you possess. Before diving in, make sure you're equipped with the right foundation. Here's what you'll need to get the most out of your learning journey. Below, you can find what you should know before starting reading this book. ::::{grid} 1 1 1 3 :class-container: text-center :gutter: 3 :::{grid-item-card} :link-type: doc :class-header: bg-light Programming Fundamentals ✏️ ^^^ - Variables, data types, and operators - Control flow (loops, conditionals) - Functions and basic algorithms - Familiarity with Python syntax - OOP[^oop] experience ::: :::{grid-item-card} :link-type: doc :class-header: bg-light Technical Setup ✨ ^^^ - Computer with internet access - Python installed[^pythonv] ::: :::{grid-item-card} :link-type: doc :class-header: bg-light Learning Mindset πŸ” ^^^ - Curiosity and willingness to experiment - Patience with debugging and errors - A few hours per week for practice ::: :::: [^oop]: If you don't know what *OOP* is, this book is not for you yet. [^pythonv]: I will use the most recent version (as of the time of writing) Python 3.13. However, most of the knowledge here will be valid also for previous versions, otehrwise I will notify you explicitly. ## Recommended Preparation ```{admonition} Not quite ready? :class: tip prereq-tip If you're missing some prerequisites, don't worry! Here are some resources to help you catch up: - **Python Basics**: [Python.org Tutorial](https://docs.python.org/3/tutorial/) - **Software Engineering Basics**: If you can read in **polish**, my book about software engineering fundamentals in Python may be helpful: > Walczak, J. (2023). Elementy inΕΌynierii oprogramowania w Pythonie. Helion. - **Python Bootcamps**: Many online platforms offer intensive Python bootcamps for beginners - **Python Online Courses**: There is a variety of free online resources that will help you get acquainted with Python ``` ## How Is This Book Organized? At the very beginning of each chapter, I will list specific prerequisites you should satisfy to fully understand the content. Then, I will go through the theory, enriching it with examples. ## What Will You Learn from This Book? ::::{grid} 1 1 2 2 :gutter: 3 :::{grid-item-card} [Special Attributes & Methods](special_attributes.md) 🏷️ :class-header: bg-light Those famous `__dunder__` attributes and methods for modules, classes, methods, and other Python objects ::: :::{grid-item-card} [Context managers](context_managers.md) πŸ”’ :class-header: bg-light Usage of `with` keyword and their potential applications and limits ::: :::{grid-item-card} [Iterators](iterators.md) πŸ”„ :class-header: bg-light Iterating over sources of data ::: :::{grid-item-card} [Generators](generators.md) ⚑️ :class-header: bg-light Generating content and `yield` keyword ::: :::{grid-item-card} [Generic collections](generics.md) πŸ“¦ :class-header: bg-light Type-safe collection handling ::: :::{grid-item-card} [Structural subtyping](structural_subtyping.md) πŸ‘£ :class-header: bg-light Creating protocols and mechanisms behind the, ::: :::{grid-item-card} [Higher-Order Functions](higher_order_functions.md) πŸ”„ :class-header: bg-light Functions that take or return a function ::: :::{grid-item-card} [Decorators](decorators.md) 🎨 :class-header: bg-light Syntactic sugar, preceded by closures ::: :::{grid-item-card} [Metaclasses](metaclasses.md) πŸ—οΈ :class-header: bg-light A vital element in dynamic programming ::: :::{grid-item-card} [Descriptors](descriptors.md) πŸ“‹ :class-header: bg-light Including the popular `@property` ::: :::{grid-item-card} [Code inspection](code_inspect.md) πŸ” :class-header: bg-light Stack tracing, callable signature management, and more ::: :::{grid-item-card} [Dynamic code execution](dynamic_execution.md) ⚑ :class-header: bg-light And its pros and cons ::: :::{grid-item-card} [Weak references](weakref.md) πŸ”— :class-header: bg-light For caching and other purposes ::: :::{grid-item-card} [Coroutines and concurrency](coroutines_and_concurrency.md.md) ⏭️ :class-header: bg-light And their applications ::: :::{grid-item-card} [Parallel Execution](parallelism.md) πŸš€ :class-header: bg-light Mastering multi-threaded and multi-process programming ::: :::: ## Requesting Topics & Reporting Errors If you come across an error or would like to suggest a new topic, simply click the πŸ’‘ icon in the top menu bar.
