Python format negative currency

问题

I haven't found anything that addresses how to format negative currency, so far, and it is driving me crazy.

from decimal import *
import re
import sys
import os
import locale


locale.setlocale( locale.LC_ALL, 'English_United States.1252' )
# cBalance is a running balance of type Decimal

fBalance = locale.currency( cBalance, grouping=True )
print cBalance, fBalance

Result with Negative Number:

-496.06 ($496.06)

I need a minus sign NOT parenthesis

How do I get rid of the parenthesis and get minus signs?

回答1:

Looks like you can use the _override_localeconv dict (which is a bit hackish).

import locale

cBalance = -496.06

locale.setlocale( locale.LC_ALL, 'English_United States.1252')
locale._override_localeconv = {'n_sign_posn':1}

fBalance = locale.currency(cBalance, grouping=True)
print cBalance, fBalance

or you could use string formatting.

This may not be the comprehensive approach you seek, but if you use the locale en_US.UTF-8, you can have a deterministic approach with the the negative sign -:

import locale
locale.setlocale(locale.LC_ALL, b'en_US.UTF-8')

amount = locale.currency(-350, grouping=True)
print(amount) # -$350.00

amount = locale.currency(-350, grouping=True).replace('$', '')
print(amount) # -350.00
