Modifying logging message format based on message logging level in Python3

Question

I asked this question for python 2 here, but bumped into the issue again when the the answer no longer worked for Python 3.2.3.

Here\'s code that works on Python 2.7.3:<

Answer 1

I am quiet late for this question but here is my solution. It follows the original python 2 syntax style. In general there are three new classes that you should be using due to the addition of styles support. Those are: PercentStyle, StrFormatStyle, and StringTemplateStyle.

from logging import Formatter, PercentStyle, ERROR, WARNING, INFO, DEBUG
class SrvLogFormat(Formatter):
    def __init__(self):
        super().__init__(fmt=env.fmt_log, datefmt=env.fmt_log_date)

    def format(self, record):
        original_style = self._style

        if record.levelno == DEBUG:
            self._style = PercentStyle(env.fmt_dflt)
        if record.levelno == INFO:
            self._style = PercentStyle(env.fmt_dflt)
        if record.levelno == WARNING:
            self._style = PercentStyle(env.fmt_dflt)
        if record.levelno == ERROR:
            self._style = PercentStyle(env.fmt_err)

        result = Formatter.format(self, record)
        self._style = original_style
        return result
