Python Distilled (Developer's Library)

Expert insight for modern Python (3.6+) coding from the author of Python Essential Reference
Python educator Dave Beazley’s concise handbook focuses on the essential core of the Python programming language, with code examples to illuminate how Python works and how to structure programs that can be more easily explained, tested, and debugged. Rather than trying to cover every possible feature and quirk of a 30-year-old language, this pragmatic guide provides a concise narrative related to fundamental programming topics that form the foundation for Python projects of any size including
Data abstraction
Control flow
Program structure
Functions: master functions and functional programming idioms
Objects: control objects and master the "protocols" that define their behavior
Modules: plan for project growth by understanding modules and packages
Generators
