zahlwort2num 0.2.0

A small package for handy conversion of german numerals (also ordinal / signed) written as words to numbers.

zahlwort2num (v. 0.2.0)

:de: :de: :de: A small but useful (due shortage of/low quality support for lang_DE) package for handy conversion of german numerals (incl. ordinal number) written as string to the from numbers.

To put it differently: It allows reverse text normalization for numbers.

This package might be a good complementary lib to https://github.com/savoirfairelinux/num2words

:crying_cat_face: Currently is doesn't support swiss variant. TBD :switzerland:

Installation

pip2 install zahlwort2num

Usage

Definition:

import zahlwort2num as w2n

Example:

w2n.convert("Zweihundertfünfundzwanzig") # => 225
w2n.convert("neunte") # => '9.' 
w2n.convert("minus siebenhundert Millionen achtundsiebzig") # => -700000078

or even stuff like:

w2n.convert("sechshundertdreiundfünfzigtausendfünfhunderteinundzwanzig") # => 653521

:see_no_evil:

Command line:

• (Obviously it is better to use a parameter enclosed with apostrophs due to possible spaces)

bin/zahlwort2num-convert "eine Million siebenhunderteinundzwanzig"

WIKI

TBD

Already implemented features :sunglasses:

• Theoretically it works for any numbers from range 0 upto 999 * 10^27 [big numbers]
• Command-line mode (see above)
• Supported with ordinal numerals (incl. inflections [sufficies like 'ste', 'ten' etc. ])
  In this case it returns coerced String type value e.g '15.' instead of Integer :point_up:
• Relative mild rules in terms of trailing whitespaces, lower/upper-case (unification).
• Handling of signed numerals (also ordinal ones) e.g 'minus zehn'

TODO / Known issues

• Make POC, functional for all common cases
• Ordinal number support
• Take care for exceptions / trailing whitespaces etc.
• Make structure + publish as PyPI package
• Command line support :computer:
• More comprehensible tests
• Swiss variant
• More fault tolerant (ß -> ss) etc
• Larger scale than 10^60
• Ordinal with very large numbers (without addons) e.g Millionste
• Few benchmark improvements (e.g tail recursion etc)
• Better error handling + validation for idiotical cases (e.g minus null Miliarde)
• Simplify/refactor POC code, add better documentation
• Fractions?
