Sequential GUIDS in Python
:param long val: The value to pack :param str endianness: The endianness of the result. “’big’“ for big-endian, “’little’“ for little-endian. If you want byte- and word-ordering to differ, you’re on your own. Using :ref:`string formatting` lets us use Python’s C
Field Types
Data validation and settings management using python 3.6 type hinting However, as can be seen above, pydantic will attempt to ‘match’ any of the types defined under Union and will use the first one that matches. In the above example the id of user_03 was defined as a uuid.UUID class (which is defined under the attribute’s Union annotation) but as the uuid.UUID can be marshalled into an int it
