Recently, in writing a program that uses Python to generate apps, it is found that printing information directly with print is less convenient and prescriptive, so using the logging log module, simply record the usage, The Logging.config configuration log should be used in a formal project to achieve log file size limits like log4j, format control, output location, and so on.1. Simply print the log to the s

Objective It is believed that every programmer should know that when using Python to write background tasks, it is often necessary to use an output log to record the state of the program running, and to save the details of the error in case of an error to debug and analyze. The Python logging module is a good helper in this case. The
