Python ConfigParser 模块重命名一个部分

Question

如何重命名ConfigParser对象中的部分？

Answer 1

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)

Answer 2

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

Answer 3

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)
