How to join hex values

Question

I am reading four bytes from file I would like to join them

g = f.read(60)
f.seek (60)
k60 =f.read(1)
print('byte60',k60)
k61 =f.read(1)
print('byte61',k61)
k62 =f.read(1)
print('byte62',k62)
k63 =f.read(1)
print('byte63',k63)
print(k63,k62,k61,k60)
print (b''.join([k63,k62,k61,k60]))

Result is:

b'\x00\x00\x00\x80'

I would like to receive:

00000080

no it is not, I do not want sum them but them next of each other without "\x" — Pr0bit Marcin Idzik, Mar 17 '16 at 20:05
Give us your input file and the results of `print('byte6x',k6x)`. — Plouff, Mar 18 '16 at 07:49

You to convert a byte string to its hex representation, you can use the hexlify() method from the binascii module:

>>> from binascii import hexlify
>>> ...
>>> raw = b''.join([k63,k62,k61,k60])
>>> print(hexlify(raw))
b'00000080'
>>> print(hexlify(raw).decode('ascii')  # if you want to convert it to a string
00000080

The same could be accomplished by using codecs.encode(raw, 'hex').
