A parser for Japanese number (Kanji, arabic) in the natural language.
The module japanese_numbers finds any numbers in the natural language, and converts to arabic numerals. The followings are example patterns what can be parsed.
- 二千万百一円
- 5百万
- 一を聞いて十を知る
- 五〇六号室
pip install japanese-numbers-python
Function to_arabic and to_arabic_numbers are almost stable.
to_arabic returns An array of [japanese_numbers.result.ParsedResult].
import japanese_numbers
japanese_numbers.to_arabic('銀河の向こう、六千三百二十一億千五百十一万二千百八十一光年彼方。')
# => [<ParsedResult 632115112181 : "六千三百二十一億千五百十一万二千百八十一" index=7>]
japanese_numbers.to_arabic('一を聞いて十を知る。')
# => [<ParsedResult 1 : "一" index=0>, <ParsedResult 10 : "十" index=5>]Then you can see a numeric value (and others) in the instance of ParsedResult like as follows:
result = japanese_numbers.to_arabic('一を聞いて十を知る。')
result[0].number # => 1
result[0].text # => '一'
result[0].index # => 0 as position that number was found
result[1].number # => 10
result[1].text # => '十'
result[1].index # => 5to_arabic_numbers returns a tuple of numbers directly.
import japanese_numbers
japanese_numbers.to_arabic_numbers('一を聞いて十を知る。')
# => (1, 10)Both to_arabic_numbers, to_arabic get encode option to specify encode of input.
It's utf8 by default, if you put non-unicode string into functions, it will be converted to unicode by using its encode first.
japanese_numbers.to_arabic_numbers('一を聞いて十を知る。') # utf8 by default
japanese_numbers.to_arabic('一を聞いて十を知る。', encode='eucjp') # set another charset- support float/double types
- support negative types
