Many applications have log modules, which are used to record some key information about the system during its operation, so as to track the running status of the system. This article mainly introduces the use of the logging log module in a multi-process environment in Python. For more information, see the following. Many applications have log modules, which are used to record some key information about the

Python prints all property values for an object: def prn_obj (obj): print ' \ n '.
