I wish to convert it to a long integer, treating it as base-256.

It is really a shame that there is not a standard library function
for this. I usually do it using hexadecimal conversion:
d = int(s.encode('hex'), 16)

Not that it helps you right now, but provided someone finds the time,

I have a byte string (Python 2.x string), e.g.:
s = "g%$f yg\n1\05"
assert len(s) == 10
I wish to convert it to a long integer, treating it as base-256.
Currently I'm using:
def makelong(s):
n = 0
for c in s:
n *= 256
n += ord(c)
return n
which gives:
>>> makelong
