Hello guys
I would like to read a hex number from an ASCII file, increment it and
write it back.
How can this be performed?
I have tried several approaches:
my file serial.txt contains: 0C
--
f = open('serial.txt', 'r')
val = f.read()
val = val.encode('hex')
val = val.encode('hex')
That's the crucial line -- it's returning a new integer, which you are
re-binding to val. If you then did:
val = val + 1
you'd be fine, and could then write val back to your file :-)

No, it returns another string, which still isn't the decimal
representation of the hex

Of course - my apologies, I was being an idiot.
