Fw: Undeliverable Message

[Matthew_WARREN at bnpparibas.com]

Hallo pyPeople,

I wrote a little snippet of code that takes a list representing some
'digits', and according to a list of symbols, increments the digits through
the symbol list.

so for example,

digits=["a","a","a"]
symbols=["a","b","c"]


increment(digits,symbols) repeatedly would return digits as

aab
aac
aba
abb
abc
aca


etc..

Heres the code

def increment(digits,symbols):
        overflow=True
        digitpos=-1
        while overflow and -digitpos<=len(digits):
                digitsymbolindex=symbols.index(digits[digitpos])
                if digitsymbolindex==len(symbols)-1:
                        overflow=True
                        digits[digitpos]=symbols[0]
                        digitpos=digitpos-1
                else:
                        digits[digitpos]=symbols[digitsymbolindex+1]
                        overflow=False
        return digits



Now, this works. All good. It's nice and simple.  I'm just wondering how
anyone else might approach it?


Matt.
