Question

How can I use struct.unpack() or some other function available in Python to easily convert one byte variable to a Python integer? Right now, it is done in a rather lame way:

file = open("telemetry.dat", "rb").read()
magic = file[0]
int(binascii.hexlify(magic), 16)

Is there another?

Answer 1

how about ord(my_byte) ?

Or if the variable content is like my_byte == "0xff" or ff
you can simply do int(my_byte, 16)

If you have a streamof hex digits, you can do:

int_bytes = (int(my_bytes[i:i+2], 16) for i in xrange(0, len(my_bytes), 2) )
