Hi,
If you want to define your own function, no matter what the length of
the number is or what separator you want to choose, this will work:

def conv(s, sep='.'):
    start=len(s)%3
    last=start
    result=s[0:start]
    for i in range(start+1,len(s)):
        if (i-start)%3==0:
            if last==0:
                result+=s[last:i]
            else:
                result+=sep+(s[last:i])
            last=i

    if last==len(s) or last==0:
        result+=s[last:len(s)]
    else:
        result+=sep+s[last:len(s)]
    return result

print conv('1234567890000000')
print conv('1')
print conv('123')
print conv('1234')
>>>
1.234.567.890.000.000
1
123
1.234
