Greetings:

I am writing a function that accepts a string of decimal digits, calculates a checksum and r
eturns it as a single character string.  
The first step in the calculation is to split the input into two strings: the even- and odd-
 numbered digits, respectively.  The least significant digit is defined as odd.  

The following code fragment does the job but seems sort of brutish and inelegant to me:

> >>>>>>
> >> s = '987654321'
> >> odd = ''
> >> for c in s[::-2]:
...     odd = c + odd
...     
> >> s = s[:-1]
> >> even = ''
> >> for c in s[::-2]:
...     even = c + even
...     
> >> odd
'97531'
> >> even
'8642'
> >>>>>>

Is there a better (i.e. more Pythonic) way to do this?  

Thanks in advance for all your help.

Regards,
