How to log the contents of a ConfigParser?

Question

How can I print the contents of a Python 2.7 ConfigParser to logging?

The only solution I can find is to write to a temporary file and read that file back in. Another idea I had was to get a fake "file handle" from the logging utility and pass that to the ConfigParser write method, but I don't know how to get such a handle form logging.

Answer 1

As this is the top Google search result and I was hoping to find a solution to print the values of the ConfigParser instance to stdout, here's a one-liner to help all future readers:

print({section: dict(config[section]) for section in config.sections()})

You should be able to create a writable object that writes to the log. Something like this (if you want to keep the string around you could modify the ConfigLogger to save it as well):

import ConfigParser import logging  class ConfigLogger(object):     def __init__(self, log):         self.__log = log     def __call__(self, config):         self.__log.info("Config:")         config.write(self)     def write(self, data):         # stripping the data makes the output nicer and avoids empty lines         line = data.strip()         self.__log.info(line)  config = ConfigParser.ConfigParser() config.add_section("test") config.set("test", "a", 1) # create the logger and pass it to write logging.basicConfig(filename="test.log", level=logging.INFO) config_logger = ConfigLogger(logging) config_logger(config) 

This yields the following output:

INFO:root:Config: INFO:root:[test] INFO:root:a = 1 INFO:root:
