Strings and Console I/O in Python

1. Challenge

   Get oriented with the starter project

   Welcome to the lab. You will complete a small Python console application that turns a few simple building blocks into a polished interactive workflow. info> This lab experience was developed by the Pluralsight team using an internally developed AI tool. All sections were verified by human experts for accuracy prior to publications. However, content may still contain errors or inaccuracies, and we recommend independent verification.

2. Challenge

   Create static output with strings

   This step focuses on the simplest but most important building block in the lab: text. Before a program can become interactive, it needs readable static output, such as titles, welcome lines, and banners.

3. Challenge

   Gather text input from the user

   With the banner in place, the next phase is interactivity. This step teaches the core idea that user input enters a Python program as text, and that prompt design affects both usability and program structure.

4. Challenge

   Parse numeric input and calculate totals

   So far, every value gathered from the user has stayed as text. That works well for names and genres, but quantities and prices need a different treatment because the program must do math with them.

5. Challenge

   Assemble the final workflow

   The last step brings the application together. Up to this point, you have built small focused helpers for title text, prompts, formatting, parsing, and arithmetic. Now that you've finished the application, it's time to test the complete experience from start to finish.

   Run the application from the Terminal tab:

   python3 app/booth_helper.py
   

   As you interact with the program, verify that it can:

   • Display the book fair banner and welcome message.
   • Prompt for a visitor's name and favorite genre.
   • Show a personalized message based on the visitor's interests.
   • Collect the number of books being purchased and the price per book.
   • Calculate the subtotal correctly.
   • Print a complete visit summary with all the collected information.

   Try a few different inputs and confirm that the final summary reflects the values you entered and that the subtotal is calculated correctly. If everything works as expected, you've successfully completed the lab!
