In the past few articles in the Python series, we've learned a lot about working with regular expressions in Python. In this article, we'll explain how we could use python regular expressions for a realistic task. We'll do a step by step walk through on how we can build Python data structures from formatted flat [...]


This article is part of a series of articles on Python Regular Expressions. This article is a continuation on the topic and will build on what we've previously learned. In this article we'll discuss: Working with Multi-line strings / matches Greedy vs. Non-Greedy matching Substitution using regular expressions In the first article of this series, [...]


Regular expressions as a concept is not exclusive to Python at all. Python, however, does have some nuances when it come to working with regular expressions. This article is part of a series of articles on Python Regular Expressions. In the first article of this series, we will focus on discussing how we work with [...]


A common idiom in programming is sorting a list. Python makes this a very simple task. Python provides a built-in sorted() function that accepts an iterable type, and return a sorted list: First, try sorting a list: >>> l = [3, 2, 5 ,4, 7, 1] >>> sorted(l) [1, 2, 3, 4, 5, 7] Next, [...]
