guid GUID to hex-string and back

I'm new to pythonPython and I'm trying to convert between Microsoft GUIDs and plain hex strings. My code (python 3) looks like this:

def hex_to_guid(hex):
    h = binascii.unhexlify(hex)
    return '-'.join(map(bytes.decode, map(
        binascii.hexlify, (h[0:4][::-1], h[4:6][::-1], h[6:8][::-1], h[8:10], h[10:]))))


def guid_to_hex(guid):
    g = binascii.unhexlify(guid.translate(str.maketrans('', '', '-')))
    return ''.join(map(bytes.decode, map(
        binascii.hexlify, (g[3::-1], g[5:3:-1], g[7:5:-1], g[8:]))))

I suspect this may not beebe very readable. Am I being too clever?
