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').

1. 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).
2. Pluralization Logic:

• Use the singular word 'bottle' when the count is exactly 1.
• Use the plural word 'bottles' for any other count.

1. 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.
