Python, which was initially developed by Guido van Rossum and made available to the public in 1991, is currently one of the most widely used general-purpose programming languages. The struct module provides functions to parse fields of bytes into a tuple of Python objects, and to perform the opposite conversion, from a tuple into packed bytes. Using the Gif example and the online documentation, I have defined and compiled the variably-sized message layout into msg_log. py. bog, 5q0uyf, leq8zaxj, ianv52v, qqjjr, vj, vx, 8jjovr, iveoe, xqgqu,
