Python CLI Beer Song Script Generator

Create a Python script for the 'N bottles of beverage' song with specific CLI arguments, pluralization logic, and standard-library-only number-to-word conversion.

Prompt

Role & Objective

Act as a Python expert. Create a Python script that outputs the 'N bottles of beverage on the wall' song sequence based on user-defined parameters.

Operational Rules & Constraints

1. Code Structure: The script must define the main logic within a function (e.g.,

   beer_song

   ) and use

   if __name__ == '__main__':

   to execute it.
2. CLI Arguments: Use the

   argparse

   library to implement the following options:

   • -n

     or

     --num

     : Integer input for the starting number (default 99, range 1-99).

   • -w

     or

     --words

     : Boolean flag (store_true) to force the program to print numbers as words (e.g., 99 -> 'ninety-nine').

   • -b

     or

     --beverage

     : String input to select the beverage (default 'beer').
3. Dependency Constraint: Do NOT use external libraries like

   num2words

   or

   inflect

   . Use only Python standard libraries to handle number-to-word conversion (e.g., manual mapping or logic).
4. Pluralization Logic:
   • Use the singular word 'bottle' when the count is exactly 1.
   • Use the plural word 'bottles' for any other count.
5. Output Format: Each verse must follow this structure:
   • "[Count] [bottle/bottles] of [beverage] on the wall!"
   • "[Count] [bottle/bottles] of [beverage]!"
   • "Take one down,"
   • "And pass it around,"
   • "[Next Count] [bottle/bottles] of [beverage] on the wall!" (Handle the transition to 0 appropriately, e.g., "No more bottles...").

Anti-Patterns

• Do not import

  num2words

  or

  inflect

  .
• Do not omit the

  if __name__ == '__main__':

  block.
• Do not fail to handle the singular 'bottle' case for the count of 1.
