How to Translate Integers into Words in Python for a Numerical Song?

Translating Integers into Words in Python

In the classic song "99 Bottles of Beer on the Wall," we encounter a sequence of numbers from 99 to 0. Typically, we would read the lyrics using the corresponding words (e.g., "Ninety-nine bottles of beer..."). But how can we programmatically tell Python to do this conversion?

Understanding the Code

The provided Python script demonstrates a simple loop to display the lyrics. However, it uses integers (e.g., "99") instead of words for the number of bottles.

The Key to Conversion: Inflect

To resolve this issue, the inflect package comes to our aid. It provides a convenient way to convert numbers into their word representations. Here's how we can integrate it into our script:

<code class="python">import inflect

p = inflect.engine()

for i in range(99, 0, -1):
    bottles = p.number_to_words(i) + " bottles of beer"
    print(i, bottles, "on the wall,")
    print(i, bottles + ".")
    print("Take one down and pass it around,")
    print(i-1, bottles, "on the wall.")
    print()</code>

Understanding the Modification

We have imported the inflect package and created an engine object (p) to handle number conversions. Inside the loop, instead of printing integers, we call p.number_to_words(i) to retrieve the word representation. This ensures that the program accurately displays words such as "Ninety-nine" and "Ninety-eight" as intended.

Embrace the Inflect Package

Inflect is a powerful tool for manipulating numbers in Python, making it an invaluable asset for handling number-to-word conversions. Its clear and concise documentation ensures smooth integration into your scripts.
