This article will show you how to use the Python reduce() function to aggregate data from values in an iterable (iterables are things like lists, dictionaries, sets, or tuples – collections containing items that can be looped over) and reduce them to a single accumulated value. The code and examples in this tutorial will work in Python 3. Syntax for Python reduce() functools.reduce(FUNCTION, ITERABLE[, INITIALIZER]) Note that: FUNCTION is a standard Python function, previously defined in your code It should accept two parameters The first parameter is the current accumulated value up until this point … Read more

This article will explain how to use recursion in Python functions, with some example code to illustrate the concept. A recursive function is a function which calls itself one or more times until a condition is met. If a function that uses recursion calls itself too many times, Python will throw an error. As this is a demonstration of a code structure rather than anything with any specific syntax, I’ll show a simple example of a recursive function and leave comments explaining what is going on.
