Example use

from commentedconfigparser import CommentedConfigParser

# Load the config like normal
config = CommentedConfigParser()
config.read("myconfig.ini")

# Use the config like normal
...

# Update the config like normal
...

# Save the config back to the file
with open("myconfig.ini", "w") as savefile:
    config.write(savefile)

Results

We favor the line spacing choices of the ConfigParser class so the input format may not be preserved completely. However, the comments will be preserved.

Before

# Welcome to our config
[DEFAULT]
# This value has some meaning to someone
foo=bar
# Make sure to add this when you need it
trace=false
logging=true
; This is a comment as well

    # so we need to track all of them

	; and many could be between things
[NEW SECTION]
# Another comment
multi-line=
	value01
	value02
	value03
closing=0
# Trailing comment

# Welcome to our config
