Try format in the locale module:

format(format, val[, grouping])

Formats a number val according to the current LC_NUMERIC setting. The 
format follows the conventions of the % operator. For floating point 
values, the decimal point is modified if appropriate. If grouping is 
true, also takes the grouping into account.

The "grouping" parameter is what you are looking for.
