[Solved] Convert number to words with Python

To convert a number to words, you can use a simple algorithm that involves dividing the number into groups of three digits (using the modulus operator % and division /) and then converting each group of three digits to words. Here’s some pseudocode that shows how this can be done:

def convert_number_to_words(number):
  if number == 0:
    return "zero"
  if number < 0:
    return "negative " + convert_number_to_words(-number)

  result = ""
  groups = []
  while number > 0:
    groups.append(number % 1000)
    number = number / 1000

  group_names = ["", "thousand", "million", "billion", "trillion"]

  for i in range(len(groups)):
    group = groups[i]
    if group > 0:
      result = convert_three_digits_to_words(group) + " " + group_names[i] + " " + result

  return result.strip()

def convert_three_digits_to_words(number):
  digits = [
    "", "one", "two", "three", "four", "five", "six", "seven", "eight",
    "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen",
    "sixteen", "seventeen", "eighteen", "nineteen"
  ]
  tens = [
    "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty",
    "ninety"
  ]

  result = ""
  if number >= 100:
    result = digits[number / 100] + " hundred"
    number = number % 100

  if number >= 20:
    result = result + " " + tens[number / 10]
    number = number % 10

  if number > 0:
    result = result + " " + digits[number]

  return result.strip()

This algorithm works by dividing the number into groups of three digits and then converting each group to words using the convert_three_digits_to_words function. The convert_three_digits_to_words function converts a number between 0 and 999 to words by breaking it down into hundreds, tens, and ones.
