I am looking to format a number like 188518982.18 to £188,518,982.18 using Python.
How can I do this?
This question is related to

formatting
currency
See the locale module.
This does currency (and date) formatting.
>>> import locale
>>> locale.setlocale( locale.LC_ALL, '' )
'English_United States.1252'
>>> locale.currency( 188518982.18 )
'$188518982.18'
>>> locale.currency( 188518982.18, grouping=True )
'$188,518,982.18'
#printing the variable 'Total:' in a format that looks like this '9,348.237'
print ('Total:', '{:7,.3f}'.format(zum1))
where the '{:7,.3f}' es the number of spaces for formatting the number in this case is a million with 3 decimal points. Then you add the '.format(zum1). The zum1 is tha variable that has the big number for the sum of all number in my particular program. Variable can be anything that you decide to use.
"{:0,.2f}".format(float(your_numeric_value))
in Python 3 does the job; it gives out something like one of the following lines:
10,938.29
10,899.00
10,898.99
2,328.99
A lambda for calculating it inside a function, with help from @Nate's answer
converter = lambda amount, currency: "%s%s%s" %(
"-" if amount < 0 else "",
currency,
('{:%d,.2f}'%(len(str(amount))+3)).format(abs(amount)).lstrip())
and then,
>>> converter(123132132.13, "$")
'$123,132,132.13'
>>> converter(-123132132.13, "$")
'-$123,132,132.13'
Oh, that's an interesting beast.
I've spent considerable time of getting that right, there are three main issues that differs from locale to locale: - currency symbol and direction - thousand separator - decimal point
I've written my own rather extensive implementation of this which is part of the kiwi python framework, check out the LGPL:ed source here:
http://svn.async.com.br/cgi-bin/viewvc.cgi/kiwi/trunk/kiwi/currency.py?view=markup
The code is slightly Linux/Glibc specific, but shouldn't be too difficult to adopt to windows or other unixes.
Once you have that installed you can do the following:
>>> from kiwi.datatypes import currency
>>> v = currency('10.5').format()
Which will then give you:
'$10.50'
or
'10,50 kr'
Depending on the currently selected locale.
The main point this post has over the other is that it will work with older versions of python. locale.currency was introduced in python 2.5.
My locale settings seemed incomplete, so I had too look beyond this SO answer and found:
http://docs.python.org/library/decimal.html#recipes
OS-independent
Just wanted to share here.
>>> '{:20,.2f}'.format(18446744073709551616.0)
'18,446,744,073,709,551,616.00'
Simple python code!
def format_us_currency(value):
value=str(value)
if value.count(',')==0:
b,n,v='',1,value
value=value[:value.rfind('.')]
for i in value[::-1]:
b=','+i+b if n==3 else i+b
n=1 if n==3 else n+1
b=b[1:] if b[0]==',' else b
value=b+v[v.rfind('.'):]
return '$'+(value.rstrip('0').rstrip('.') if '.' in value else value)
"{:0,.2f}".format(float(your_numeric_value))
in Python 3 does the job; it gives out something like one of the following lines:
10,938.29
10,899.00
10,898.99
2,328.99
Not quite sure why it's not mentioned more online (or on this thread), but the Babel package (and Django utilities) from the Edgewall guys is awesome for currency formatting (and lots of other i18n tasks). It's nice because it doesn't suffer from the need to do everything globally like the core Python locale module.
The example the OP gave would simply be:
>>> import babel.numbers
>>> import decimal
>>> babel.numbers.format_currency( decimal.Decimal( "188518982.18" ), "GBP" )
£188,518,982.18
If you are using OSX and have yet to set your locale module setting this first answer will not work you will receive the following error:
Traceback (most recent call last):File "<stdin>", line 1, in <module> File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/locale.py", line 221, in currency
raise ValueError("Currency formatting is not possible using "ValueError: Currency formatting is not possible using the 'C' locale.
To remedy this you will have to do use the following:
locale.setlocale(locale.LC_ALL, 'en_US')
If I were you, I would use BABEL: http://babel.pocoo.org/en/latest/index.html
from babel.numbers import format_decimal
format_decimal(188518982.18, locale='en_US')
Inspired by the code above :D
def money_format(value):
value = str(value).split('.')
money = ''
count = 1
for digit in value[0][::-1]:
if count != 3:
money += digit
count += 1
else:
money += f'{digit},'
count = 1
if len(value) == 1:
money = ('$' + money[::-1]).replace('$-','-$')
else:
money = ('$' + money[::-1] + '.' + value[1]).replace('$-','-$')
return money

This is an ancient post, but I just implemented the following solution which:
Code:
num1 = 4153.53
num2 = -23159.398598
print 'This: ${:0,.0f} and this: ${:0,.2f}'.format(num1, num2).replace('$-','-$')
Output:
This: $4,154 and this: -$23,159.40
And for the original poster, obviously, just switch $
for £

for digit in value[0][::-1]:

I've come to look at the same thing and found python-money not really used it yet but maybe a mix of the two would be good
