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')
print val
----------------------------------
--> 3043
----------------------------------
f = open('serial.txt', 'r')
val = f.read()
print val
val = val+1
----------------------------------
--> TypeError: cannot concatenate 'str' and 'int' objects
----------------------------------
f = open('serial.txt', 'rb')
val = f.read()
val = val + 1
----------------------------------
--> TypeError: cannot concatenate 'str' and 'int' objects
hm....
