As author noted in comments, to pass UUID objects into cursor methods one have to call register_uuid() first once:

import psycopg2.extras

# call it in any place of your program
# before working with UUID objects in PostgreSQL
psycopg2.extras.register_uuid()

# now you can pass UUID objects into psycopg2 functions
cursor.execute("INSERT INTO MyTable (uuid) VALUES (%s)", (uuid.uuid4(),))

# ... and even get it from there
cursor.execute("SELECT uuid FROM MyTable")
value, = cursor.fetchone()
assert isinstance(value, uuid.UUID)
