#40670 — Insert comma in number?

I have a python program that accepts input and calculates the factorial of that number, and i want to know if i can make it so commas get inserted in the number.
For example: instead of 1000 it would say 1,000

pip install humanize


import humanize
my_integer = 12345678
commafied_integer = humanize.intcomma(my_integer)
print commafied_integer


output:
12,345,678

Use the "," (i.e. comma) format() specifier directive. See
http://docs.python.org/2/library/string.html#format-specification-mini-language
See also: http://www.python.org/dev/peps/pep-0378/

Cheers,
Chris

 >>> format(12345234434, ',d')
'12,345,234,434'
 >>> '{:,d}'.format(333333333333)
'333,333,333,333'

Last not least there's the option to employ locale-aware formatting:

>>> import locale
>>> locale.setlocale(locale.LC_ALL, "en_US.UTF-8")
'en_US.UTF-8'
>>> locale.format("%d", 12345, grouping=True)
'12,345'

In German usage of "." and "," is reversed, so:
 
>>> locale.setlocale(locale.LC_ALL, "de_DE.UTF-8")
'de_DE.UTF-8'
>>> locale.format("%d", 12345, grouping=True)
'12.345'

Does this locale-aware example only work on UNIX?

If you have Windows in mind: I don't know what it takes to get multiple 
locales on a Windows system, but for the default locale that you can specify 
with

locale.setlocale(locale.LC_ALL, "")

it should work.
