Functional programming

One of the great things about programming in Python is that you are never constrained to a single way of thinking about your programs. There are always various ways to solve a given problem, and sometimes the best one requires an approach that is slightly different from the one that would be the most obvious. Sometimes, this approach requires the use of declarative programming. Fortunately, Python, with its rich syntax and large standard library, offers features of functional programming, and functional programming is one of the main paradigms of declarative programming.

Functional programming is a paradigm where the program flow is achieved mainly through the evaluation of (mathematical) functions rather than through a series of steps that change the state of the program. Purely functional programs avoid the changing of state (side effects) and the use of mutable data structures.

One of the best ways to better understand the general concept of functional...
