Functions in Python are first class objects; this means that they are objects, and they each have a type, as well as a behavior. In this video, the author teaches you how to use functools.partial, function factories, and closures.
- [Instructor] In functional programming,…our main concern is not defining objects,…but managing the flow of data between functions.…One advantage of functional programming,…is that within limits, functional code is formally provable.…The correctness of its results,…can be established by analyzing it.…Also, like object-oriented programming,…functional programming helps you break problems into blocks,…and write code that is modular, composable,…debuggable, and testable.…
In this video, I will show you that in Python…functions are first-class objects,…a key feature in functional languages.…That is, functions are like any other object,…in that they can be passed as arguments to other functions,…they can be assigned to variables,…and included in lists, and so on.…I will also show you how to obtain…a derived function, known as partial,…where some of the arguments of the original function…are fixed to certain values.…Finally, I will show you how to…define higher-order functions,…that define, or modify, functions.…
