Re: [Configobj-develop] has_section function?

[Michael F. <fuz...@vo...>]

Hello Thomas,

Your email isn't spam, it's entirely on topic!

ConfigObj doesn't have those methods specifically - *however* the 
information is easy to find out.

The following tells you if an entry is in a ConfigObj instance (but not 
whether it is a section or a value):

     'foo' in configfile

For just checking for the presence of a section you can do:

     'foo' in configfile.sections

For values you can do:

     'foo' in configfile.scalars

That code works on individual sections as well as the main ConfigObj 
instance.

You could also do:

     result = configfile.get('foo')
     if result is None:
         # entry is not present
     elif isinstance(result, dict):
          # entry is present and a section
     else:
         # entry is present and a value

All the best,

Michael Foord
