log messages to an array/list with logging

Question

Currently am using python logging to log messages to a log file and to console (if --verbose).

How can I configure logging to also record messages into an array/list?

Been working on this for many hours, after posting this question I just figured it out after 30 minutes or so — Fragtzack

Figured this out after posting.
Used a Stream to a string.

Here is snippet of the code, not including the stdout Stream and the normal logger file handle:

import io
import logging

logger = logging.getLogger()
errors = io.StringIO()
formatter = logging.Formatter('%(asctime)s - %(module)s.%(funcName)s() - %(levelname)s - %(message)s',"%Y-%m-%d %H:%M:%S")
eh = logging.StreamHandler(errors)
eh.setFormatter(formatter)
logger.addHandler(eh)

logger.error("This is a test error message")
contents=errors.getvalue()
print("error string=>{}".format(contents))
errors.close()

I get 'TypeError: can't write str to text stream' with python 2.6.
