在 Python 中口头格式化一个数字 [英] Verbally format a number in Python

问题描述

pythonistas 如何将数字打印为单词，类似于 Common Lisp 代码:

[3]>(格式 t "~r" 1e25)九千亿、九百九十九千亿、九百九十九千亿、七百七十八亿亿、一千九千六亿、三千八亿、三亿六千一百万、二十万一万六千

解决方案

python 核心中没有，但是有 3rd 方库 num2words

<预><代码>>>>从 num2words 导入 num2words>>>num2words(1e25)'十个七十亿，七千三百万，七十四万一千，八百二十四'>>>num2words(10000000000000000000000000)'十节'

(注意 1e25 没有精确地转换为整数，在你的例子中也没有)

How do pythonistas print a number as words, like the equivalent of the Common Lisp code:

[3]> (format t "~r" 1e25)
nine septillion, nine hundred and ninety-nine sextillion, nine hundred and ninety-nine quintillion, seven hundred and seventy-eight quadrillion, one hundred and ninety-six trillion, three hundred and eight billion, three hundred and sixty-one million, two hundred and sixteen thousand

解决方案

no in python core, but there is 3rd party library num2words

>>> from num2words import num2words
>>> num2words(1e25)
'ten septillion, one billion, seventy-three million, seven hundred and forty-one thousand, eight hundred and twenty-four'

>>> num2words(10000000000000000000000000)
'ten septillion'

(note that 1e25 is not converted to integer precisely, neither in your example)
