Authoring technical textbooks is not a one-off effort. It requires constant nurturing. Every so often I find out that a package I used is no longer maintained and so I have to re-release an updated version of the textbook to reflect this. This weekend I updated my regression textbook. If you own a print copy and find that a package I suggest doesn't install, please consult the online version to see if I have written an update, or else please notify me via the issues page. A reminder that the full online version is completely free and open source, and if you invest in the print or ebook version, all my royalties are donated to a good cause.

🚀 #ProjectCompleted: Python Phonebook Application 📞 I'm excited to share that I've successfully built a Python-based Phonebook application that handles basic CRUD (Create, Read, Update, Delete) operations. Here's a quick overview of what the app can do: ✨ Features: 1 .Add a New Contact: Prompt the user for the name and phone number of a new contact and add it to the phonebook. If the contact already exists, it shows a message. 2. Search for a Contact: Allow the user to search for a contact by name and display the phone number. 3. Delete a Contact: Easily delete a contact by name if it exists. 4. List All Contacts: Show all contacts with their phone numbers. 5. Exit: Terminate the program with an option. 🛠️ Steps I Followed: Initialized a Python file called phonebook.py. Created an empty dictionary to store contact names as keys and phone numbers as values. Used a simple CLI with a while-loop that shows options like adding, searching, deleting, and listing contacts. Ensured seamless user interaction with condition checks for errors, such as duplicate contacts or searches for non-existent entries. Implementation Steps:- #Step 1: Setup Your Project ● Create a new Python file named phonebook.py. ● Open this file in your chosen text editor. #Step 2: Initialize the Phonebook ● At the beginning of your program, create an empty dictionary to store your contacts. Each contact name will be a key, and the associated phone number will be the value. #Step 3: User Interface ● Implement a loop that continuously displays a menu of options to the user until they choose to exit. Use input() to read the user's choice and if-else statements to handle different actions based on the choice. #Step 4: Implementing CRUD Operations ● Add a New Contact: Check if the name already exists in the dictionary. If it does, display a message; otherwise, add the new entry. ● Search for a Contact: Check if the contact exists in the dictionary. If so, display the contact's phone number; otherwise, inform the user that the contact was not found. ● Delete a Contact: Similar to search, but remove the contact from the dictionary if it exists. ● List All Contacts: Use a loop to iterate through the dictionary and display each contact's name and phone number. #Step 5: Testing ● Thoroughly test your application to ensure it handles different scenarios gracefully, such as searching for a non-existent contact or adding a contact that already exists 🔍 #SourceCode https://lnkd.in/g6ZDC6SZ 🌟 #Python #CodingJourney #ProjectComplete #PhonebookApp #Programming

The C++ I know of, is not C23. The language has evolved a lot. I found this book to be really good Beginning C++23: From Beginner to Pro, https://lnkd.in/e-p8iKrd

🚀 Just wrapped up two exciting web scraping projects in just one week! 🚀 In the past week, I’ve dived into web scraping and successfully created two unique datasets: 1️⃣ Sports Car Dataset scraped from Wikipedia 2️⃣ Books Dataset scraped from the "Books to Scrape" Website 🔍 I used requests and BeautifulSoup to gather, clean, and organize the data. It was a challenging yet rewarding learning journey!

In each programming language strings are interpreted slightly differently. This makes it a little difficult to transfer your knowledge on string operations from one programming language to the next. Go is not different and it has its quirks one must know about before mastering string manipulation. Therefore, I strongly recommend every aspiring Go programmer to read this brief article on different approaches to iterating over strings in Go. It is written by my mentor Bob Hoeppner and he explains very well the 4 main ways to do it. You will also apply this knowledge to a concrete problem: Verifying ISBN!

I'm finally getting motivated enough to complete the update on my free ebook, Essential F#. What's fascinating to me is how little has changed in the F# language between versions 6 and 8 for the Line of Business applications/websites the book is designed to help you create. Yes, .NET has changed a lot in that time to support the addition of new safer functional features into C# but the F# Core team has done a great job in protecting us from the mayhem.
