Setup simple logging in python. This logs info message to stdout and debug messages to file.
|
|
Sure it's long but this is as simple as I could make it for this outcome.
|
|
Note: We must set the root logger at DEBUG level, since it must be higher than it's children to pass them on.
|
|
Then set filehandler at debug and stream handler at info.
