format

Synopsis

format(fmt,num,grouping=0)

Returns the string obtained by formatting number num according to the format string fmt and the LC_NUMERIC setting. Except for cultural convention issues, the result is like fmt % num. If grouping is true, format also groups digits in the result string according to the LC_NUMERIC setting. For example:

>>> locale.setlocale(locale.LC_NUMERIC,'en')
'English_United 
                        States.1252'
>>> locale.format('%s',1000*1000)
'1000000'
>>> locale.format('%s',1000*1000,1)
'1,000,000'

When the numeric locale is U.S. English, and argument grouping is true, format supports the convention of grouping digits by threes with commas.
