Currency formatting in Python
PythonFormattingCurrencyPython Problem Overview
I am looking to format a number like 188518982.18 to £188,518,982.18 using Python.
How can I do this?
Python Solutions
Solution 1 - Python
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'
Solution 2 - Python
New in 2.7
>>> '{:20,.2f}'.format(18446744073709551616.0)
'18,446,744,073,709,551,616.00'
Solution 3 - Python
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
Solution 4 - Python
This is an ancient post, but I just implemented the following solution which:
- Doesn't require external modules
- Doesn't require creating a new function
- Can be done in-line
- Handles multiple variables
- Handles negative dollar amounts
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 £
Solution 5 - Python
"{: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

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.
Solution 7 - Python
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')
Solution 8 - Python
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')
Solution 9 - Python
There are already a dozen solutions here, but I believe the one below is the best, because:
- it is simple
- obeys the OS locale
- no external lib is needed
- you can make it concise
Use locale currency
:
import locale
# this sets locale to the current Operating System value
locale.setlocale(locale.LC_ALL, '')
print(locale.currency(1346896.67444, grouping=True, symbol=True)
will output in my Windows 10 configured to Brazilian Portuguese:
R$ 1.346.896,67
It is somewhat verbose, so if you will use it a lot, maybe it is better to predefine some parameters and have a shorter name and use it inside a f-string:
fmt = lambda x: locale.currency(x, grouping=True, symbol=True)
print(f"Value: {fmt(1346896.67444)}"
You can pass a locale value for the setlocale
method, but its value is OS dependent, so beware. If you are in a *nix server, you also need to check if the locale is correctly installed in the OS.
You also can turn off the symbol passing symbol=False
.
Solution 10 - Python
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:
'$10.50'
or
'10,50 kr'
Depending on the currently selected locale.
The main point this post has over the other is that it will work with older versions of python. locale.currency was introduced in python 2.5.
Solution 11 - Python
#printing the variable 'Total:' in a format that looks like this '9,348.237'
print ('Total:', '{:7,.3f}'.format(zum1))
where the '{:7,.3f}' es the number of spaces for formatting the number in this case is a million with 3 decimal points. Then you add the '.format(zum1). The zum1 is tha variable that has the big number for the sum of all number in my particular program. Variable can be anything that you decide to use.
Solution 12 - Python
Inspired by the code above :D
def money_format(value):
value = str(value).split('.')
money = ''
count = 1
for digit in value[0][::-1]:
if count != 3:
money += digit
count += 1
else:
money += f'{digit},'
count = 1
if len(value) == 1:
money = ('$' + money[::-1]).replace('$-','-$')
else:
money = ('$' + money[::-1] + '.' + value[1]).replace('$-','-$')
return money
Solution 13 - Python
I've come to look at the same thing and found python-money not really used it yet but maybe a mix of the two would be good
Solution 14 - Python
A lambda for calculating it inside a function, with help from @Nate's answer
converter = lambda amount, currency: "%s%s%s" %(
"-" if amount < 0 else "",
currency,
('{:%d,.2f}'%(len(str(amount))+3)).format(abs(amount)).lstrip())
and then,
>>> converter(123132132.13, "$")
'$123,132,132.13'
>>> converter(-123132132.13, "$")
'-$123,132,132.13'
Solution 15 - Python
Simple python code!
def format_us_currency(value):
value=str(value)
if value.count(',')==0:
b,n,v='',1,value
value=value[:value.rfind('.')]
for i in value[::-1]:
b=','+i+b if n==3 else i+b
n=1 if n==3 else n+1
b=b[1:] if b[0]==',' else b
value=b+v[v.rfind('.'):]
return '$'+(value.rstrip('0').rstrip('.') if '.' in value else value)
