Python get diff for ConfigParser

Question

Let say I have old and new configurations initialized

from ConfigParser import ConfigParser

old_config = ConfigParser()
old_config.read(config_file1)
new_config = ConfigParser()
new_config.read(config_file2)

How can I get the difference between these two configs?

Answer 1

You can turn each of the config instances into a dictionary using:

old_dict = old_config._sections
new_dict = new_config._sections

then get the difference using:

set(old_dict.items()) ^ set(new_dict.items())
