Introduction Python’s print() function is typically used to display text either in the command-line or in the interactive interpreter, depending on how the Python program is executed. However, we can change its behavior to write text to a file instead of to the console. In this article, we’ll examine the many ways we can write to a file with the print() function.

Introduction The map(), filter() and reduce() functions bring a bit of functional programming to Python. All three of these are convenience functions that can be replaced with List Comprehensions or loops, but provide a more elegant and short-hand approach to some problems. Before continuing, we’ll go over a few things you should be familiar with before reading about the aforementioned methods: What is an anonymous function/method or lambda? An anonymous method is a method without a name, i.e. not bound […]

Introduction to any() and all() In this tutorial, we’ll be covering the any() and all() functions in Python. The any(iterable) and all(iterable) are built-in functions in Python and have been around since Python 2.5 was released. Both functions are equivalent to writing a series of or and and operators respectively between each of the elements of the passed iterable. They are both convenience functions that shorten the code by replacing boilerplate loops. Both methods short-circuit and return a value as […]
