#One of the most obvious(and elegant maybe) way (done as TestFirstDesign-way) to do is,
def sep(s):
p=s.find('.')
if p==-1:
p=len(s)
for i in range(p-3,s[0] in ('+','-'),-3):
s=s[:i]+','+s[i:]
return s
#which can be made to a one-liner using RE as,
def sep(s):
return re.sub(r"([-+]?\d{1,3}(\.\d*)?)(?=(\d{3})*(\.|$))",r",\1",s)[1:]
#or we could simply use the library as,
>>> locale.setlocale(locale.LC_ALL,"")
'Korean_Korea.949'
>>> locale.format("%s",-12345.3291,1)
'-12,345.3291'
