I posted a coding challenge in the fifth issue of learnbyexample weekly. I discuss the problem and Python/Perl solutions in this blog post.

(2023-03-20) Update: This TUI app covers many more exercises compared to the GUI app discussed below.

Still confused about Python regular expressions? Grow your confidence with Understanding Python re(gex)? ebook (FREE this month!) and an interactive GUI app.

Inspired by Advent of Code, I'll also be posting 3 challenges per day on twitter for 25 days.

Hello!

Here's some exciting programming deals for my own ebooks as well sales details from other creators.

I posted a coding challenge in the second issue of learnbyexample weekly. I discuss the problem and Python/Perl solutions in this blog post.

Hello!

I'm excited to announce learnbyexample weekly newsletter, scheduled to be delivered every Friday.

This free newsletter will help you discover awesome programming resources. I'll primarily focus on resources related to Python, Linux, CLI tools, Regular Expressions and Vim. Sometimes, I'll also include other programming resources.

Hello!

You never know where a conversation between indie authors will lead to. A tweet about Leanpub Python book sales brought up giveaways that we indie authors tend to do. Long story short, the four of us ended up deciding to create The Indie Python Extravaganza bundle.

And guess what?! You can use this pytober coupon link to get the bundle for FREE (the offer is valid till 31-Oct-2021).

Hello!

I just published my ebook titled "Practice Python Projects". This book presents five beginner to intermediate level projects inspired by real world use cases:

• Enhance your CLI experience with a custom Python calculator
• Analyzing poll data from a Reddit comment thread
• Finding typos in plain text and Markdown files
• Creating a GUI for evaluating multiple choice questions
• Square Tic Tac Toe — creating a GUI game with AI

I'm building a tool called rcut that allows you to use cut like syntax with features like regexp based delimiters. The solution uses awk inside a bash script.

Latest feature creep is fixed string field splitting. I thought it would be a simple enough solution to add.

I was wrong.

This post covers Basic Regular Expressions (BRE) and Extended Regular Expressions (ERE) syntax supported by GNU grep, sed and awk. You'll also learn the differences between these tools — for example, awk doesn't support backreferences within regexp definition (i.e. the search portion).

TL;DR: Small victories are more precious when you have nothing. Instead of burning through my savings, I'm now adding to it. The relief is priceless.
