[Configobj-develop] how to define key/value at the top level following use of Sections

[Bob S. <Bob...@ou...>]

I have searched extensively and not found anything that answers the following:

In creating a config file with nested Sections, how can I later in the file return to defining items (i.e., key/value pairs) at the top-level section?

E.g., if in the following file:

# --------------- start thisFile.ini
top1 = 100
top2 = 200
[LEVEL1]
Level1A = 1000

[LEVEL2]
Level2A = 2000

# Now I want top3 to be defined in the top level, rather than in Section [LEVEL1][LEVEL2]
top3 = 200

# ---------------- end thisFile.ini


When the config file is processed, cfg=ConfigObj('thisFile.ini'), I'd like top3 to be cfg['top3'], instead of as cfg['LEVEL1']['LEVEL2']['top3'].  My only guess was to change the last 2 lines to:

[]    # hoping maybe return to top level ?
top3 = 200

...  but that does not work and causes  an exception.  So as best I can determine it seems that all top-level definitions must precede any use of a Section.
Is that actually correct, or is there a way to return to defining items at the top level?

Thanks in advance for any help or advice.
