Conditionals in Python

1. Challenge

   Step 1: Explore the starter project

   You are building a small Python CLI for an indoor adventure park check-in desk. Starting from a set of placeholder functions, you will implement comparison helpers, conditional message builders, and multi-branch decision functions — then combine them into a complete visit summary for sample guests.

   The project is split into focused modules: app/comparisons.py holds boolean helpers, app/messages.py builds optional summary lines, app/classification.py handles multi-branch logic, app/report.py combines the results, and app/main.py prints the output.

   If you need assistance, solutions for each task can be found in the solutions directory.

   Step 2: Create reusable comparison helpers

   Boolean helper functions wrap a single comparison and return True or False, giving business rules a readable name and making them easy to test. In this step, you implement three helpers in app/comparisons.py — each returning a comparison result directly.

   You will:

   • Implement an equality comparison (==)
   • Add a minimum-height check with an inclusive operator (>=)
   • Detect when a credit balance falls below a required amount (<)

   Step 3: Add optional messages with simple if statements

   A simple if block runs its indented code only when the condition is true. When the condition is false, Python skips the block and continues — so the base output is always produced. In this step, you use if statements to append optional lines to a guest summary in app/messages.py.

   You will:

   • Add a membership bonus line for members only
   • Show a prize counter message when credits exceed a threshold
   • Append an equipment rental note when stock is available

   Step 4: Build multi-branch classifications

   When a program must select exactly one result from several categories, an if/elif/else chain evaluates conditions in order and runs only the first matching branch. Branch order and boundary operators determine which category each input receives. In this step, you implement three classifiers in app/classification.py.

   You will:

   • Classify guests into climbing zones by height
   • Assign ticket bands by age range
   • Report locker availability across three distinct states

   Step 5: Integrate the helpers into a working CLI

   app/report.py imports the helpers from earlier steps and assembles their output into a single multi-line summary. app/main.py loops through sample guests and prints each summary. In this step, you complete both files to produce a working end-to-end CLI.

   You will:

   • Combine all helpers into a single visit summary function
   • Loop through sample guests and print formatted output with separators between them
