Greetings: I am writing a function that accepts a string of decimal digits, calculates a checksum and returns 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.
