Each network interface has a unique MAC address. Identifier given to a network interface that has been attached to a physical network segment. Python | Convert String to bytes Last Updated: 22-05-2019 Inter conversions are as usual quite popular, but conversion between a string to bytes is more common these days due to the fact that for handling files or Machine Learning ( Pickle File ), we extensively require the strings to be converted to bytes. If MAC address string is not in valid format, it returns NULL. it relies on size of byAddress and it must be greater than 6 bytes. Const char cSep = '-' //Bytes separator in MAC address string like 00-aa-bb-cc-dd-ee /* This function accepts MAC address in string format and returns in bytes. UUID ( '' ) > # convert a UUID to a string of hex digits in standard form > str ( x ) '00010203-0405-0607-0809-0a0b0c0d0e0f' > # get the raw 16 bytes of the UUID > x. When a string of hex digits is given, curlyīraces, hyphens, and a URN prefix are all optional. Time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bitĬlock_seq_low, 48-bit node) as the fields argument, or a single 128-bit
The bytes_le argument, a tuple of six integers (32-bit time_low, 16-bit
UUID ( hex=None, bytes=None, bytes_le=None, fields=None, int=None, version=None ) ¶Ĭreate a UUID from either a string of 32 hexadecimal digits, a string of 16īytes as the bytes argument, a string of 16 bytes in little-endian order as Note that uuid1() may compromise privacy since it createsĪ UUID containing the computer’s network address. If all you want is a unique ID, you should probably call uuid1() or Generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122. This module provides immutable UUID objects (the UUID class)Īnd the functions uuid1(), uuid3(), uuid4(), uuid5() for uuid - UUID objects according to RFC 4122 ¶
