possibly avoid closing as this answer contains actual code to solve the issue - not the case for the linked question — bph, Mar 05 '13 at 12:21
I found the answer here: http://docs.python.org/3/library/argparse.html#sub-commands. Using sub-commands resolves the issue — Hendré, Nov 13 '13 at 16:32

example helper function - silly really but it might save someone a few minutes work...

def rename_section(cp, section_from, section_to):
    items = cp.items(section_from)
    cp.add_section(section_to)
    for item in items:
        cp.set(section_to, item[0], item[1])
    cp.remove_section(section_from)

As far as I can tell, you need to

get the sections items via ConfigParser.items
remove the section via ConfigParser.remove_section
create a new section via ConfigParser.add_section
Put the items back into the new section via ConfigParser.set

i thought as much - where is cp.set_section("old_name", "new_name") when you need it? – bph Feb 25 '13 at 14:31
@Heitt -- Yeah. I've not spent a lot of time reading the configparser source, but it seems like that wouldn't be terribly hard to accomplish. I honestly have always felt like there is a bunch of functionality to configparser which seems like it could be added without much trouble. – mgilson Feb 25 '13 at 14:33

You can use the private method _sections to rename it in a single line.

def rename_config_section(config, old_section, new_section):
    """Rename a section in a configparser object."""
    config._sections[new_section] = config._sections.pop(old_section)
