Write a Python program that prints each digit of a number as a word.

Input

Output

one zero two four

Approach

Map each digit character to its word with a list.

Solution

Python

words = ["zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"]n = 1024result = []for ch in str(n):    result.append(words[int(ch)])print(" ".join(result))

Output

one zero two four

Line by line

Line 1

The list index is the digit, so words[4] is “four”.

Line 4

Looping over str(n) gives the digits from left to right.
