在Python中用数字格式化一个数字 [英] Verbally format a number in Python

问题描述

python如何打印一个数字作为单词，就像Common Lisp代码的等价物一样：

  [3]> （格式t〜r1e25）
九次九，九九九，九九九，七百七十八万亿，十九万六千，三百和80亿，3110万，2116万美元， python核心中没有，但有第三方库 num2words  
 >>> from num2words import num2words 
>>> num2words（1e25）
'十亿，十亿，七千三百七十四万一千八百二十四'
 
>>> num2words（10000000000000000000000000）
'ten septillion'
  
（注意1e25不会被转换为整数确切地说，在你的例子中）
 
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)
