One question per day _python. Using yield generator to implement the TPS transparent transfer CS Test under the co-process

Specific requirements:
1. Analog device first sends the registration package registered to the TPS server, then the client sends a private packet to the TPS, and the test device can receive a private packet to return the success or the flag bit (0, ') or (1, ' errormsg ')
2. Since this plug-in is used for its own write plug-in monitoring system, so the entry function name must be consistent with the file name, which is tentatively server_tps_status.py

Implementation ideas:
