Words to Numbers

The challenge is simple: Convert numbers into their word form, with no tricks like libraries, packages, caching, etc.

The "Words to Numbers" project is a challenging Python script that converts numbers (greater than 0) into their word form only with a single line of code. Originally aimed to produce this program in under 90 lines in Python, I refined and rewrote it over and over to achieve its final state.

Installation

To set up the project environment and run the script, you must have Poetry installed. If you do not have Poetry, you can install it by following the instructions here.

After installing Poetry, clone this repository to your local machine:

git clone https://your-repository-url/words_to_numbers.git
cd words_to_numbers
poetry install    # No dependencies to install

Usage

To run the script, use the following command:

poetry run python -m words_to_numbers

Features

• Single-Line Conversion: The core feature of this script is its ability to convert numbers into words in a single line of Python code.
• Expanding: Expanding the range of the program's output is simple, just add more elements to the 3 lists each currently created as

[ "", "hundred ", "thousand ", "million ", "billion ", "trillion ", "quadrillion ", "quintillion ", "hextillion ", "septillion "]

and increment the number 9 found in 3 different places within the program, all in places with boilerplate:

if (
    0
    if (len(x) - i) == 1
    else (
        (0 if x[i] == "0" else 1)
        if (len(x) - i) % 3 == 0
        else (
            (((len(x) - i) - 4) // 3) + 2
            if ((len(x) - i) - 4) % 3 == 0
            and (
                x[i] != "0"
                or x[i if (i - 1) < 0 else i - 1] != "0"
                or x[i if (i - 2) < 0 else i - 2] != "0"
            )
            else 0
        )
    )
) > 9:       # Update the 9 in 3 locations all with this context (expanded version)
