![]() You can see that we have generated the random id. Print("The random id using uuid1() is : ") Otherwise, a random 14-bit sequence number is chosen. If clock_seq is given, it used as the sequence number.If a node not given, then the uuid.getnode() function is used to obtain the Universally administered MAC addresses of a current host. The node is the hardware address, which is the 48-bit positive integer.The node and clock_seq are optional arguments.Syntax uuid.uuid1(node=None, clock_seq=None) Parameters Python UUID module provides uuid1() method that generates the random id using the MAC address and time component. UUID.SafeUUID : SafeUUID.unknown Generate Random IDs using UUID.uuid1() Print('UUID.clock_seq : ', UUID.clock_seq) Print('UUID.clock_seq_low : ', UUID.clock_seq_low) Print('UUID.clock_seq_hi_variant: ', UUID.clock_seq_hi_variant) Print('UUID.time_hi_version : ', UUID.time_hi_version) Let’s extract and print the above information for uuid.uuid1(). clock_seq_hi_variant : Next 8 bits of id.time_hi_version: The next 16 bits of id.variant: It is a variant determining the internal layout of UUID.version: It is the version number of UUID.hex: Returns the random id as 32 character hexadecimal string.int: Returns id in the form of a 128-bit integer.bytes: Returns id in the form of 16-byte string.UUID4 uses the pseudo-random number generators to generate UUID.The UUID 3 uses MD5 hashing, and UUID 5 uses the SHA-1 hashing. ![]() UUID3 and UUID5 use cryptographic hashing and application-provided text strings to generate UUID.The uuid1 version uses the IEEE 802 MAC addresses. UUID1 generates UUID using a Host MAC address, serial(sequence) number, and the current time.Python UUID module provides the following versions of UUIDs.
