New submission from Nic Watson:
The assertion:
File "/usr/lib/python3.6/uuid.py", line 150, in __init__
assert isinstance(bytes, bytes_), repr(bytes)
is too specific (and IMHO, unpythonic). One may want to pass a bytearray or a
memoryview. See int.from_bytes for an example that takes "bytes" but accepts
anything that acts like a bytes.
A simple solution may be to delete the assertion (it worked for me).
Example code:
import uuid
b = uuid.uuid1().bytes
ba = bytearray(b)
print(uuid.UUID(bytes=b))
# another API that works similarly, accepts a bytearray
print(int.from_bytes(ba, byteorder='big'))
# fails on assertion
print(uuid.UUID(bytes=ba))
