1 PrefaceIn the previous section, we introduced the state of program execution. From the example, we can find that there are clear policies to follow when processing these state changes. Here we will introduce them. 2. Details2.1 activity-no

Python implements the method for monitoring program execution time and writing it into logs, and the python Monitoring Program This example describes how to implement the execution time of a monitoring program in Python and write it into logs.

Clock (): The time it takes to capture a call from the beginning of the program to the clock (). This unit of time is clock tick, which is called "clocking".Constant CLK_TCK: The number of clock ticks per second that the machine clock has

Main () function, presumably everyone is not strange, from the beginning of the program, we began to write main (), we all know that main is the entrance of the program. That main as a function, and who calls it, how it is called, returned to whom,
