Verbally format a number in Python

Question

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 nin         


        

Answer 1

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)
