text2num
text2num
is a python package that provides functions and parser classes for:
- Parsing of numbers expressed as words in French, English, Spanish, Portuguese, German and Catalan and convert them to integer values.
- Detection of ordinal, cardinal and decimal numbers in a stream of French, English, Spanish and Portuguese words and get their decimal digit representations. NOTE: Spanish does not support ordinal numbers yet.
- Detection of ordinal, cardinal and decimal numbers in a German text (BETA). NOTE: No support for 'relaxed=False' yet (behaves like 'True' by default).
Compatibility
Tested on python 3.7. Requires Python >= 3.6.
