Byte-Array

[DeaD_EyE]

I guess there is no one right way how you can solve this task.

You can work with binascii.hexlify

from binascii import hexlify


ba = bytearray(b'\xd0\x13t')
hexstr = hexlify(ba).decode() # hexlify returns bytes
print(hexstr)

Another method could be str-formatting:

ba = bytearray(b'\xd0\x13t')
hexstr = ''.join(format(integer, 'x') for integer in ba) 
print(hexstr)

For Python 3.6 fans with format string interpolation:

ba = bytearray(b'\xd0\x13t')
hexstr = ''.join(f'{integer:x}' for integer in ba) 
print(hexstr)
