What You Will Learn How to harness Python’s full power to write exceptionally robust and well-performing code. The Pythonic way of writing programs, building on a fundamental understanding of Python to help you write programs more effectively. The core Python language, and the most essential parts of the Python library. How to utilize the Python 3.x library to jump-start application development. How to elegantly code powerful solutions succinctly and efficiently with Python.
Core Concept Using the concise, scenario-driven style pioneered in Scott Meyers’ best-selling Effective C++, Brett Slatkin brings together 59 Python best practices, tips, and shortcuts, and explains them with realistic code examples. Hands-on demonstration of a broad but related set of items designed to provide concise and specific guidance on what to do and what to avoid when writing programs using Python. Accurate and concise reference to the most important parts of Python. Presents selected examples from the hundereds of modules in the Python standard linrary demonstrating how to use the most commonly used features of the modules that support Python’s 'batteries included' slogan. Provides developers with an approach to programming in Python that expresses big ideas succinctly, with the minimum of code, allowing the business logic to shine through.
Key Topics Covered Best practices for writing functions that clarify intention, promote reuse, and avoid bugs; Expressing behaviors with classes and objects; Avoid pitfalls with metaclasses and dynamic attributes; Efficient approaches to concurrency and parallelism; Techniques and idioms for using Python’s built-in modules; Tools and best practices for collaborative development Methods; Comprehensions and generators; Functions and classes; Concurrency and parallelism; How to make programs more robust Language features, libraries, and modules; Generators, coroutines, closures, metaclasses, and decorators; How to use Python 2.6’s forward compatibility mode to evaluate code for Python 3 compatibility; Low-level system and networking library modules Python 3.x’s new libraries, significant functionality changes, and new layout and naming conventions. Expert porting guidance for moving code from 2.x Python standard library modules to their Python 3.x equivalents. Newer features from Python 3.6, including f-strings and type hinting; ETL (extract-transform-load) techniques to prepare real-world data for analysis; How to improve code reliability
Python Versions Covered 3.x and 2.x Python 3 Python 2.6 and 3.0. Omits features of Python 2 that have been removed from Python 3. Does not features of Python 3 that have not been back-ported.

Editorial Reviews

From the Back Cover

Python Essential Reference is the definitive reference guide to the Python programming language ― the one authoritative handbook that reliably untangles and explains both the core Python language and the most essential parts of the Python library.

Designed for the professional programmer, the book is concise, to the point, and highly accessible. It also includes detailed information on the Python library and many advanced subjects that is not available in either the official Python documentation or any other single reference source.


Thoroughly updated to reflect the significant new programming language features and library modules that have been introduced in Python 2.6 and Python 3, the fourth edition of Python Essential Reference is the definitive guide for programmers who need to modernize existing Python code or who are planning an eventual migration to Python 3. Programmers starting a new Python project will find detailed coverage of contemporary Python programming idioms.


This fourth edition of Python Essential Reference features numerous improvements, additions, and updates:

  • Coverage of new language features, libraries, and modules
  • Practical coverage of Python's more advanced features including generators, coroutines, closures, metaclasses, and decorators
  • Expanded coverage of library modules related to concurrent programming including threads, subprocesses, and the new multiprocessing module
  • Up-to-the-minute coverage of how to use Python 2.6’s forward compatibility mode to evaluate code for Python 3 compatibility
  • Improved organization for even faster answers and better usability
  • Updates to reflect modern Python programming style and idioms
  • Updated and improved example code
  • Deep coverage of low-level system and networking library modules ― including options not covered in the standard documentation
