If you have ever wanted to use Python list comprehensions, but were unsure of the syntax or exactly how they worked, then this tutorial is aimed at you.  This tutorial aims to walk you through the basics of how Python list comprehensions work with three real world examples.  In the tutorial below I have three examples of the power of Python list comprehensions;  The first example illustrates how to setup and create a basic list comprehension.  The second example get's a lot more complex and uses two nes

One of the nice new feature enhancements in Swift 4 this year is Proposal 172 for One-sided Ranges. Proposal 172, in Swift Evolution, now simplifies collection manipulation by giving developers the option to pick from using the verbosity of the start and endIndex or using the newly implemented syntax that infers the start and end index for you.

Swift 4 is packed with all kinds of great updates to the Swift Standard Library's Dictionary type thanks to the great work put in by Nate Cook to enhance the Dictionary and Set types in proposal 165 of Swift Evolution.

If you have ever wondered how to find a substring inside another string in C++ then hopefully this tutorial will help walk you through how to do that.  As an example, in C++, if you have ever wondered how to determine if the substring "Agnosticdev," is part of the parent string "Hello Agnosticdev, I love Tutorials," then this tutorial will show you how to indicate, with an unsigned integer, the index of the first character in the substring.

With the release of Swift 4 next week and the implementation of proposal 168 now up and running in the Swift 4 toolchain I thought it would be nice to get in and get my hands dirty with multi-line string literals to provide some examples on how standard string manipulation practices now work with multi-line string literals in Swift 4.  This tutorial will focus on some of the general operations developers use in working with and string manipulation for day to day tasks in development.
