I wrote a TUI application to help you practice Python regular expressions. There are more than 100 exercises covering both the builtin re and third-party regex module.

If you have pipx, use pipx install regexexercises to install the app. See the repo for source code and other details.

 

Hello!

I am pleased to announce a new version of my Linux Command Line Computing ebook.

This ebook aims to teach Linux command line tools and Shell Scripting for beginner to intermediate level users. The main focus is towards managing your files and performing text processing tasks. Plenty of examples are provided to make it easier to understand a particular tool and its various features. There are 200+ exercises to help you practice what you've learned and solutions are provided for reference. I hope this ebook would make it easier for you to discover CLI tools, features and learning resources.

I would highly appreciate it if you'd let me know how you felt about this book. It could be anything from a simple thank you, pointing out a typo, mistakes in code snippets, which aspects of the book worked for you (or didn't!) and so on. Reader feedback is essential and especially so for self-published authors.

Happy learning :)

When I was younger, I'd read slowly, trying to visualize the setting, keep track of character preferences, look up words I don't know, etc. I'd remember a book well enough to talk about it even a year or so after.

These days, I just skim over descriptions and read as fast as I could while still getting the main plot. I get attached to characters only if the book is really good and savor them during rereads.

I mostly read fantasy and sci-fi, which tend to have multiple books in a series. If they are easy-to-read and short (300-400 pages per book), it becomes easy to consume. Also, I read for escapism, so I don't read too closely.

Hopefully less than this year. I'm reading too many (100+) and that's reflecting in my reduced time on actual work (self-employed).

I have a list of curated resources here: https://learnbyexample.github.io/py_resources/

There are sections for beginners, intermediate, advanced, etc. Also included are exercises, projects, debugging, testing, and many more stuff. Hope it helps :)

+1 for Cradle already mentioned. I'd add

  • The Riyria Revelations by Michael J. Sullivan
  • Kings of the Wyld by Nicholas Eames

It's the name of the constructor, for example:

const pat1 = new RegExp(`42//?5`)

So, I used that in the book name.

That's great to hear and thanks for the kind feedback :)

I used to use it for posting on Twitter, with some keywords (like book title) in bold.
