This article will detail how to use the ‘accumulate()’ function in Python and provide some easy-to-follow example code. The accumulate() function in Python will process an iterable (iterables are things like lists, dictionaries, sets, or tuples – collections containing items which can be looped over) – returning the… Read More »Using the Python ‘accumulate()’ Function to Aggregate Data, With Examples

This article will cover the syntax and usage of the filter function. It will work for both Python 2 and Python 3. The filter function in Python takes an iterable (iterables are things like lists, dictionaries, sets, or tuples – collections containing items that can be looped over) and checks… Read More »Using the Python ‘filter()’ Function to Filter a List, with Examples

This article will explain the map() function in Python and show you how to use it. The Python map() function applies a given function for all items in an iterable (iterables are things like lists, dictionaries, sets, or tuples – collections containing items that can be looped over). The syntax… Read More »Using the Python ‘map()’ Function to Process a List, With Examples

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… Read More »Using the Python ‘reduce()’ Function to Aggregate Data, With Examples

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… Read More »Using Recursion/Recursive Functions in Python, with Examples

This tutorial covers converting Bytes to a string variable (and a string to Bytes) in Python versions 2 and 3. What is the difference between a string and a byte string? A string is a series of characters. When stored on disk, the characters are converted to a series of bytes. What… Read More »Converting Bytes To String In Python [Guide]

This article explains how to check the type of a variable in the Python programming language. What are Types? The type of a variable determines what it can or can’t do. It determines what value the variable may take and what can be done with that value. Using the type() Function… Read More »Checking Type in Python [Guide]
