Python UUID Module Usage example

The UUID is a unique identity that is used in many areas as an identity. Python's UUID module is used to generate it.
Gossip does not say that Python provides a total of 4 ways to generate UUID, namely:

1. Generate from hardware address and time
2. Generating from the MD5 algorithm
3. Randomly generated
4. Generating from the SHA-1 algorithm

They correspond to UUID1, UUID3, Uuid4, UUID5 These methods in the UUID module, noting that there is no uuid2.
Here's an example:
Copy the Code code as follows:

#-*-encoding:gb2312-*-
Import UUID

Print Uuid.uuid1 ()
Print UUID.UUID3 (UUID. Namespace_dns, ' Testme ')
Print Uuid.uuid4 ()
Print UUID.UUID5 (UUID. Namespace_dns, ' Testme ')
