My wrapper code

[quentinjs]

I figured I'd contribute back, this has worked on 5,000 legal documents from many sources. Here is a wrapper I wrote to help supportmy W2N.. Some of this is related to typos in the original documents or badly scanned.

in my case I don't care about pennies so I removed the 100/xx type text. hope this helps someone.

def word2value(val): tens = [ 'twenty', 'thirty', 'forty', 'fifty','sixty', 'seventy', 'eighty', 'ninety']

my_name = sys._getframe().f_code.co_name

if val is not None and len(val) > 0:
    val = re.sub("\$,", "", val).lower()

    # remove 00/100 or other values
    val = re.sub(r' AND \d+\/100(ths|th)?', '', val, flags=re.IGNORECASE)
    val = re.sub(r' & \d+\/100(ths|th)?', '', val, flags=re.IGNORECASE)
    val = re.sub(r' AND NO\/100?', '', val, flags=re.IGNORECASE)

    # e.g. four hundred AND two
    if val.isnumeric(): #or val.find('and') != -1:
        return val

    val = re.sub("^venty", "seventy", val, flags=re.IGNORECASE)

    val = re.sub("^irty", "thirty", val, flags=re.IGNORECASE)

    # fix hyphenated words so they include the hyphen
    for t in tens:
        while True:
            m = val.find(t)
            dash_pos = m + len(t)
            if m != -1 and len(val) > dash_pos and val[dash_pos:dash_pos+1].isalpha():
                val = val[:dash_pos ] + '-' + val[dash_pos:]
            else:
                break

    try:

    except ValueError as e:
        pass
