First, Introduction Multi-threaded programming technology can realize code parallelism, optimize processing capabilities, and a smaller function can make the reusability of the code better. Python threading and queue modules can be used to

Program Flow At its simplest level, the Python interpreter operates in a similar manner, starting at the top of the program, and then executing the program statement sequentially, line by line. For example, listing 1 shows a few simple statements.
