Recently modified the logging related functions in the project and used the logging module in the Python standard library to make some records here. Mainly from official documents and StackOverflow to find some of the content. Official documents Technical Blog Basic usageThe following code shows the most basic usage of

For Python, there have been two problems that have plagued me these days:There is no way to get the current line number and function name directly in 1.python. This is a question raised in the Forum, a group of people are just guessing why Python does not provide __line__ and __func__ like __file__, but ultimately did not find a solution.2. If a function does not

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
