Python logging level

# 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.
