Python debugging in Linux Python has its own pdb library for simple debugging. The basic commands are similar to gdb, but the functions are not as powerful as gdb. pdb mainly supports multi-breakpoint settings (conditional settings ), code-level single-step debugging, viewing stack information, code viewing, post-mortem debugging, For more information, see: http:

Python Linux signal programming signals, pythonsignals1. Signal Introduction The Soft Interrupt signal (signal) is used to notify the process of an asynchronous event. Processes can call kill to send Soft Interrupt signals to each other. The kernel can also send a signal to the process due to internal events to notify the process of an event. Note that the signal is only used to notify a process of events
