# python logging level
Level: NOTSET > DEBUG > INFO > WARNING > ERROR > CRITICAL
Value: 0 > 10 > 20 > 30 > 40 > 50
Logger.setLevel() specifies the lowest-severity log message a logger will
handle, where debug is the lowest built-in severity level and critical is
the highest built-in severity.
For example, if the severity level is INFO, the logger will handle only INFO,
WARNING, ERROR, and CRITICAL messages and will ignore DEBUG messages.
