logging.info和logging.getLogger（）。info之间有什么区别？

Question

I am a fresh man of python.

If logging.info() is enough for logging, why we have to instantiate a logger with getLogger() method?

Answer 1

Calling getLogger() without a name returns the root logger :

Return a logger with the specified name or, if no name is specified, return a logger which is the root logger of the hierarchy .

Calling the module-level info() function logs directly to the root logger :

Logs a message with level INFO on the root logger .

If you have no use for specifically named loggers (for example in order to identify the emitting module of the log), the two calls are exactly equivalent.
