This is a basic library used for NLP that can perform conversions between numbers in numerical format and alphabetical / character format.

Installation

Usage

importing the module

from numericnormalizer import normalizer

Convert a number to a word (i.e. 5 -> 'five')

normalizer.number_to_word(5, lang='en')
>> "five"


normalizer.number_to_word(5, lang='zh')
>> "五"

Convert a word to a number (i.e. 'five' -> 5)

normalizer.word_to_number('five', lang='en')
>> 5


normalizer.number_to_word('五', lang='zh')
>> 5

Format numbers in a sentence

Example 1: default formatting

normalizer.format_sentence(
    sentence='What are the 6 principles of intercultural adaption?',
    lang='zh'
)
>> "What are the six (6) principles of intercultural adaption?"

Example 2: Custom Formatting

normalizer.format_sentence(
    sentence='I have 4 apples and five oranges.',
    lang='zh',
    formatting='{number} [{word}]',  # custom formatting
)
>> "I have 4 [four] apples and 5 [five] oranges."

Example 3: Number restricting

normalizer.format_sentence(
    sentence='I have 4 apples and five oranges.',
    lang='zh',
    max_number=4  # restrict the max_number
)
>> "I have four (4) apples and five oranges."
