You know Python’s syntax, but when it comes to real projects you freeze or second-guess yourself. You are not alone. Many learners struggle to turn knowledge into action, even after completing tutorials or coursework. What if you could practice daily with focused challenges that build confidence, fluency, and muscle memory for writing clean, efficient, and professional Python code? 

• 50 focused exercises: build muscle memory for core and advanced language features. 

• Built-in data structures: write shorter, faster code with lists, tuples, dictionaries, and sets. 

• Functional techniques: unlock map, filter, and comprehensions for elegant data pipelines. 

• Object-oriented drills: design, create, and extend classes that stay maintainable. 

• Iterators and generators: process large data streams while saving memory and time. 

• Full solutions and explanations: verify your approach and learn professional idioms. 

Python Workout by veteran instructor Reuven M. Lerner offers a practical, workbook-style route to skill mastery.

Each self-contained challenge targets a specific concept, then walks you through a clear, annotated solution. The progressive sequence mirrors real coding tasks so readers advance naturally from fundamentals to powerful patterns.

Finish the book able to read, refactor, and write Python that stands up in production code reviews. The habits you form here stick because you learn by doing, not by memorizing.

Ideal for developers who know basic syntax and need fluency for work, study, or personal projects.
