adding numbers together in a string

[Thekid]

I know python has math functions like 5+6 and 5*6 and 5/6 etc...but I have something like this:
x=575124357

and need to add them all together:
5+7+5+1+2+4+3+5 +8=40

Following are two ways:

>>> x=575124357
>>> reduce(lambda x, y: x+y, [int(s) for s in str(x)], 0)
39
>>> sum([int(s) for s in str(x)])
39
>>>

Thanks again...! I like the simpler look of the sum([int]) line so I think I'll use that.
