I receive the data as
{ "name": "Unknown", "parent": "Uncategorized", "uuid": "06335e84-2872-4914-8c5d-3ed07d2a2f16" }, and I need to convert the uuid from String to uuid
I did not find a way on the python docs, or am I missing something basic here?

uuid1() is defined in UUID library and helps to generate the random id using MAC address and time component. bytes : Returns id in form of 16 byte string. int : Returns id in form of 128-bit integer. hex : Returns random id as 32 character hexadecimal string.
If all you want is a unique ID, you should probably call uuid1() or uuid4() . Note that uuid1() may compromise privacy since it creates a UUID containing the computer's network address. uuid4() creates a random UUID. Depending on support from the underlying platform, uuid1() may or may not return a “safe” UUID.
The thread-unsafe part of Python 2.5's uuid. uuid1() is when it compares the current current timestamp to the previous timestamp. Without a lock, two processes can end up comparing against the same globally saved timestamp.
Just pass it to uuid.UUID:
import uuid o = { "name": "Unknown", "parent": "Uncategorized", "uuid": "06335e84-2872-4914-8c5d-3ed07d2a2f16" } print uuid.UUID(o['uuid']).hex Don't call .hex on the UUID object unless you need the string representation of that uuid.
>>> import uuid >>> some_uuid = uuid.uuid4() >>> type(some_uuid) <class 'uuid.UUID'> >>> some_uuid_str = some_uuid.hex >>> some_uuid_str '5b77bdbade7b4fcb838f8111b68e18ae' >>> type(some_uuid_str) <class 'str'> Then as others mentioned above to convert a uuid string back to UUID instance do:
>>> uuid.UUID(some_uuid_str) UUID('5b77bdba-de7b-4fcb-838f-8111b68e18ae') >>> (some_uuid == uuid.UUID(some_uuid_str)) True >>> (some_uuid == some_uuid_str) False You could even set up a small helper utility function to validate the str and return the UUID back if you wanted to:
def is_valid_uuid(val): try: return uuid.UUID(str(val)) except ValueError: return None Then to use it:
>>> some_uuid = uuid.uuid4() >>> is_valid_uuid(some_uuid) UUID('aa6635e1-e394-463b-b43d-69eb4c3a8570') >>> type(is_valid_uuid(some_uuid)) <class 'uuid.UUID'> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
