Converting an Integer to a Sequence of Letters with Python: A Helpful Guide

Have you ever found yourself in a situation where you need to convert an integer into its corresponding sequence of letters? This is a common requirement in many programming tasks, and today, we will explore how to achieve this in Python.

The Challenge

The problem was presented by a fellow programmer seeking to create a function that takes an integer (for instance, 234) and returns it as letters. The desired output for the input 234 should be cde instead of line-separated individual letters.

Existing Code

The user had attempted a solution but was facing difficulties in two main areas:

Mapping the numeric components to their corresponding letters using a dictionary.

Returning the final result as a single string, rather than printing the letters on separate lines.

Here is the code provided by the user:
