Python scripts are used to monitor the content of real-time files. Next, I will introduce the Python script to process log files in real time through this article. For more information, see this Python script for real-time file content monitoring, for example, the Error or time out fields can be customized. it is my fi
The following is an article about Python scripts. Similarly, there are differences between different languages. The language is just a tool. You need to select different tools based on different tasks and use Prolog as an expert system, C is used for interaction with the underlying operating system, and Java or Python is used for cross-platform communication.
