Description:

Turns integers up to the length of 10 digits into words like one hundred and ten. Also if you wish to convert a telephone number into words it will accept an eleven digit number if the first number is a 0.

Code:

import string number = "921458" number2 = "07961445111" SingleDigits = ["zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"] CountingTens = ["ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"] DoubleDigits = ["ten", "twenty", "thrity", "fourty", "fifty", "sixty", "seventy", "eighty", "ninety"] def NumberToWords(number): try: int(number) length = len(number) if length > 11: output = "number too big" elif length == 11: if number[0] == "0": output = SingleDigits[0] + " " + ThousandsMillionsToWords(number[-10:]) else: output = "too big and not a local telephone number" elif length == 10: ThousandsMillions = number[-10:] output = ThousandsMillionsToWords(ThousandsMillions) elif length == 9: HundredsMillions = number[-9:] output = HundredsMillionsToWords(HundredsMillions) elif length == 8: TensMillions = number[-8:] output = TensMillionsToWords(TensMillions) elif length == 7: Millions = number[-7:] output = MillionsToWords(Millions) elif length == 6: HundredsThousands = number[-6:] output = HundredsThousandsToWords(HundredsThousands) elif length == 5: TensThousands = number[-5:] output = TensThousandsToWords(TensThousands) elif length == 4: Thousands = number[-4:] output = ThousandsToWords(Thousands) elif length == 3: Hundreds = number[-3:] output = HundredsToWords(Hundreds) elif length == 2: Tens = number[-2:] output = TensToWords(Tens) elif length == 1: output = SingleDigits[number[-1:]] except ValueError: output = "invalid number" return string.join(string.split(output)).capitalize() def ThousandsMillionsToWords(number): if number[0] == "0": return HundredsMillionsToWords(number[-9:]) return ThousandsToWords(number[:4]) + " Million " + \ HundredsThousandsToWords(number[-6:]) def HundredsMillionsToWords(number): if number[0] == "0": return TensMillionsToWords(number[-8:]) return HundredsToWords(number[:3]) + " Million " + \ HundredsThousandsToWords(number[-6:]) def TensMillionsToWords(number): if number[0] == "0": return MillionsToWords(number[-7:]) return TensToWords(number[:2]) + " Million " + \ HundredsThousandsToWords(number[-6:]) def MillionsToWords(number): if number[0] == "0": return HundredsThousandsToWords(number[-6:]) return SingleDigits[int(number[0])] + " Million " + \ HundredsThousandsToWords(number[-6:]) def HundredsThousandsToWords(number): if number[0] == "0": return TensThousandsToWords(number[-5:]) print number[:3] return HundredsToWords(number[:3]) + " Thousand " + \ HundredsToWords(number[-3:]) def TensThousandsToWords(number): if number[0] == "0": return ThousandsToWords(number[-4:]) return CountingTens[int(number[:2])] + " Thousand " + \ HundredsToWords(number[-3:]) def ThousandsToWords(number): if number[0] == "0": return HundredsToWords(number[-3:]) return SingleDigits[int(number[0])] + " Thousand " + \ HundredsToWords(number[-3:]) def HundredsToWords(number): if number[0] == "0": return TensToWords(number[-2:]) if number[-2:] == "00": return SingleDigits[int(number[0])] + " Hundred " return SingleDigits[int(number[0])] + " Hundred and " + TensToWords(number[-2:]) def TensToWords(number): if number[0] == "0": return DigitToWords(number[-1:]) elif number[0] == "1": return CountingTens[int(number[1])] elif number == "10": return CountingTens[0] else: return DoubleDigits[int(number[0])-1] + " " + SingleDigits[int(number[1])] def DigitToWords(number): return SingleDigits[int(number)] print NumberToWords(number2)
