storing logger messages in a string

Question

I wanted to store all the intermediate log messages (warn, info, error) to a string in python and finally at the end of program, display everything as a report to the consol

You can also write your own stream class. As https://docs.python.org/2/library/logging.handlers.html says, only writeand flushare used for the streaming.

Example:

import logging

class LogStream(object):
    def __init__(self):
        self.logs = ''

    def write(self, str):
        self.logs += str

    def flush(self):
        pass

    def __str__(self):
        return self.logs

log_stream = LogStream()
logging.basicConfig(stream=log_stream, level=logging.DEBUG)

log = logging.getLogger('test')
log.debug('debugging something')
log.info('informing user')

print(log_stream)

Outputs:

DEBUG:test:debugging something
INFO:test:informing user
