Hi all,
I read in some conversations that the struct module maybe helpful in
converting Hex values to binary or decimal. Maybe I understood it
Here is my problem.
I have a 22 byte data packet on a tcp socket connection. My data field is
from the 6th byte to byte 20. 14 bytes in total.
The first two bytes of the data is a 16 bit value. Eg: "\xe2\x01'
I can the first byte into binary if I use 'e2', but I don't know how to get
the '\x' out of the first byte to use it in python. My data has the '\x' and
all I need is the 'e2'.
Any advice of the usage of the struct module or how I can get rid of the
'\x' in my data?
Hopefully I have given enough information.
