4.17 Functional-Style Programming
Like other popular languages, such as Java and C#, Python is not a purely functional language. Rather, it offers “functional-style” features that help you write code which is less likely to contain errors, more concise and easier to read, debug and modify. Functional-style programs also can be easier to parallelize to get better performance on today’s multi-core processors. The chart below lists most of Python’s key functional-style programming capabilities and shows in parentheses the chapters in which we initially cover many of them.
