I don't know about a large calculation time, but this seems to work: >>> def rightshift(a): ia = a[:] for i in range(len(ia)-1,0,-1): if ia[i-1] == 1 and ia[i]!=1: ia[i]=1 ia[i-1]=0 return ia

Re: [Tutor] Re: Soem list operation questions?

Though, of course, by modifying your way (using str() ), it will still work: >>> def listtoint(digits): result = 0 for digit in digits: result *= (10**len(str(digit))) ## just multiply it by 10 result += digit ## to the power of the number of digits return result >>> l

Re: [Tutor] Re: Soem list operation questions?

Yes, but your way only works when the numbers in the list are single digit: >>> def listtoint(digits): result = 0 for digit in digits: result *= 10 result += digit return result >>> listtoint([1,2,3,4]) 1234 >>> listtoint([11,22,33,44]) 13574 -- Email: singingxduck A
