Hello and thanks for reading.

I've also experienced this in Python 3.7, and I believe it to be around since 3.2.

The allow_no_value option of ConfigParser allows None values when (de)serializing configuration files. Yet calling the "items(section)" method of a ConfigParser returns empty strings for values instead of None. See below for an MRE.

Thanks,
Sean

>>> from configparser import ConfigParser
>>> a = ConfigParser(allow_no_value=True)
>>> a.add_section('foo')
>>> a.set('foo', 'bar')
>>> a.items('foo')
[('bar', '')]
>>> a.items('foo', raw=True)
[('bar', None)]
>>> a.get('foo', 'bar')
>>> list(a['foo'].items())
[('bar', None)]
