Guide to: Functional Python and Comprehension Constructs (Unabridged‪)‬

Functional Programming and Comprehensions

Functional programming is a somewhat hidden aspect of Python. Though it supports many of the functional constructs, the style is not widely adopted. On the flip side, functional programming appears to be making a resurgence because of the benefits it can provide.

Comprehensions are an alternative Pythonic construct for programming in a similar manner. These are features of Python that are commonly used instead of their functional counterparts. This book covers:

List comprehensions
Generator expressions
Set comprehensions
Dict comprehensions


Write Python code like the masters

These constructs, while not necessary per se, allow you to be more succinct, reuse code, and think about code in a different way. You will learn:

How the constructs work
When to use them
Real-life examples from the standard library
To understand other' 'code


This book covers many of these intermediate constructs that are available in Python. The book covers both Python 2 and 3. Topics include:

Functional programming
List comprehensions
Generator expressions
Set and dict comprehensions
