python – Converting Float to Dollars and Cents

python – Converting Float to Dollars and Cents

In Python 3.x and 2.7, you can simply do this:

>>> ${:,.2f}.format(1234.5)
$1,234.50

The :, adds a comma as a thousands separator, and the .2f limits the string to two decimal places (or adds enough zeroes to get to 2 decimal places, as the case may be) at the end.

Building on @JustinBarbers example and noting @eric.frederichs comment, if you want to format negative values like -$1,000.00 rather than $-1,000.00 and dont want to use locale:

def as_currency(amount):
    if amount >= 0:
        return ${:,.2f}.format(amount)
    else:
        return -${:,.2f}.format(-amount)

In python 3, you can use:

import locale
locale.setlocale( locale.LC_ALL, English_United States.1252 )
locale.currency( 1234.50, grouping = True )

Output

$1,234.50
