logging.getLevelName()

levels

Converts a numeric logging level to its name ('INFO') and a name back to a number. It works both ways.

Syntax

logging.getLevelName(level)

The result type depends on the argument: getLevelName(20) gives 'INFO' while getLevelName('INFO') gives the number 20. An unknown value raises no error but returns the string 'Level …', lowercase names included: getLevelName('info') is 'Level info'. To turn a name into a number, getLevelNamesMapping() is the safer choice.

Examples

import logging
print(logging.getLevelName(20), logging.getLevelName('INFO'))  # → INFO 20
print(logging.getLevelName(15), '|', logging.getLevelName('info'))  # → Level 15 | Level info
