in the code snippet below the Pycharm ide says:

def hexdump(src, length=16):
    result = []
    if not isinstance(src, unicode):
        digits = 2
    else:
        digits = 4
    for i in xrange(0, len(src), length):
        s = src[i:i+length]
        hexa = b' '.join(["%0*X" % (digits, ord(x)) for x in s])
        text = b''.join([x if 0x20 <= ord(x) < 0x7F else b'.' for x in s])
        result.append( b"%04X   %-*s   %s" % (i, length*(digits + 1), hexa, text))

unresolved reference 'unicode'
unresolved reference 'xrange'

why or where I can find the relevant documentation?

use range() instead of xrange(). python3 not support xrange().
if you want more advanced functionality then use numpy.arange()
