python: converting numbers to words

Question

I\'m trying to write a code that will convert numbers to words, up to 999 trillion. here is my code so far. it works up to 119, but after that things get messy. I can\'t use

Answer 1

This worked for me in Python 3.x:

print('Type any number here: ')
number = input()
int_side = number
dec_side = ''
for i in range(0, len(number)):
    if number[i] == '.':
        int_side = number[:i]
        dec_side = number[i + 1:]
        break
while not (int_side.isdigit()) or not (dec_side.isdigit()) and dec_side != '':
    dec_side = ''
    print('Only numbers are allowed! (decimals included, but not fractions)')
    print('Type any number here: ')
    number = input()
    int_side = number
    for i in range(0, len(number)):
        if number[i] == '.':
            int_side = number[:i]
            dec_side = number[i + 1:]
    user_choice = input()
int_length = len(int_side)
ones = ['', 'one ', 'two ', 'three ', 'four ', 'five ', 'six ', 'seven ', 'eight ', 'nine ']
teens = ['ten ', 'eleven ', 'twelve ', 'thirteen ', 'fourteen ', 'fifteen ', 'sixteen ', 'seventeen ', 'eighteen ',
         'nineteen ']
decades = ['', '', 'twenty ', 'thirty ', 'forty ', 'fifty ', 'sixty ', 'seventy ', 'eighty ', 'ninety ']
hundreds = ['', 'one hundred ', 'two hundred ', 'three hundred ', 'four hundred ', 'five hundred ', 'six hundred ',
            'seven hundred ', 'eight hundred ', 'nine hundred ']
comma = ['thousand, ', 'million, ', 'trillion, ', 'quadrillion, ']
word = ''
int_length = len(int_side)
dec_length = len(dec_side)
change = int_length
up_change = 0
while change > 0:
    if int_side == '':
        break
    if number == '0':
        word = 'zero'
        break
    elif change > 1 and int_side[change - 2] == '1':
        for i in range(0, 10):
            if int_side[change - 1] == str(i):
                word = teens[i] + word
    else:
        if change > 0:
            for i in range(0, 10):
                if int_side[change - 1] == str(i):
                    word = ones[i] + word
        if change > 1:
            for i in range(0, 10):
                if int_side[change - 2] == str(i):
                    word = decades[i] + word
    if change > 2:
        for i in range(0, 10):
            if int_side[change - 3] == str(i):
                word = hundreds[i] + word
    if change > 3:
        word = comma[up_change] + word
    change -= 3
    up_change += 1
word += 'point '
for i in range(0, len(dec_side)):
    for x in range(0, 10):
        if dec_side[i] == str(x):
            word += ones[x]
print(word)

This is an example:

Type any number here: 13243214.1324hk
Only numbers are allowed! (decimals included, but not fractions)
Type any number here: 13243214.1324
thirteen million, two hundred forty three thousand, two hundred 
fourteen point one three two four
