Python-Fiddle is an online Python playground where you can write, run, and share Python code directly from the browser without any need to install and maintain Python and packages on your computer. This platform was created make Python programming accessible to everyone and everywhere.
Aug 30, 2023 · The song "Fiddle About" by The Who revolves around Uncle Ernie, who describes himself as a wicked individual. He expresses his satisfaction that the person he is addressing (possibly a child) won't see or hear him as he "fiddles about."

This intro-level tutorial walks through all the steps of building a basic progressive web app, or PWA. We will be using web technologies — HTML, CSS, and JavaScript — to build a period tracking web app called "CycleTracker". Like all web apps, CycleTracker is designed to work in all browsers on all devices.
We will walk through the steps of building a fully functional web app, then progressively enhance CycleTracker to make it installable and to work even when the user is offline.
By default, PWAs are regular websites, built with the same technologies. Just like a regular websites, PWAs are linkable, discoverable via search engines, and visible in a browser. By including a manifest file and service worker, and serving the website over TLS, any website can become a PWA.
Using the languages of the web, we will create a fully functioning application that works both online and offline, both in the browsers and on the user's operating systems (OS). Like any regular website, CycleTracker is hosted on and downloadable from a web server. All we need is a text editor: CycleTracker, like all PWAs, doesn't require any additional programming language knowledge, packaging, or proprietary SDK. CycleTracker, like any PWA, can be seamlessly installed on any operating system without the need of app stores (nor app store approval and fees).
Use standard and open web technologies
Historically, for an application to be installable on an OS, such as Windows, iOS, MacOS, Linux, and Android, the applications are developed in OS-supported programming languages, like C#, .Net, Objective C, Swift, Kotlin, Java, or Python. PWAs are based on a different model: they use a single code base, written using standard open web technologies (HTML, CSS, and JavaScript) that work across OSes.
No compiling required
With most programming languages—like Java, C/C++, and Kotlin, which are commonly used for building Android apps, and Objective-C and Swift, for iOS—the code needs to be compiled and packaged into an installable format, like .exe, .dmg, .elf, and .apk, or another installable file type, depending on the operating system. Depending on the language, compiling and packaging may require the OS's SDK. PWAs use web technologies supported by every operating system that doesn't need to be packaged or compiled. Yes, developer teams can have complex build systems, but, as we will demonstrate as we build CycleTracker, PWAs can be built out of just HTML and JavaScript (and CSS, though styling is not necessarily required for a PWA).
Available anywhere and everywhere
The base web application for this PWA tutorial is a period tracker, in which the user can track the beginning and end of each menstrual cycle. We'll create a static website shell and style it, then learn how to create a secure connection to view our progress. We'll add JavaScript functionality converting the HTML and CSS shell into a fully functioning application storing data in localStorage. Using this fully functional web application you built, we will progressively enhance this web app into an offline capable PWA by adding a manifest file, including iconography, and a service worker.
The steps include:
App HTML and CSS
Line by line explanation of HTML for the static content of the website, the CycleTracker static content, along with the CSS to style that content.
Local development environment or secure connection
While all websites should be served over https, with PWAs, https is a requirement. Service workers, and therefore PWAs, are restricted to secure contexts including TLS contexts served with the https:// protocol and locally-delivered resources, including 127.0.0.1 and localhost URLs served with the http:// protocol. We will look at the page in the current state with the file:// protocol, then cover options for creating a secure localhost connection to test your code as we progress through the tutorial steps. We also look at serving your PWA with GitHub pages.
Jan 6, 2022 · The term Fiddler’s Green is one that predates this song, with its first recorded usage dating back to the mid-19 th century. Most simply put, it is a depiction of heaven as envisioned by the likes of English sailors of that day.
