python logging format: how to add bracket

Question

A quick question about Python logging format.

logging.basicConfig(filename='test.log', format='%(levelname)s %(message)s', level=logging.DEBUG)

This will give me logging messages like:

INFO Test

What I want now is to add bracket to the level name, like:

[INFO] Test

How should I modify the format argument?

Answer 1

This should do it.

logging.basicConfig(filename='test.log', format='[%(levelname)s] %(message)s', level=logging.DEBUG)
