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.
