NonelessDict¶

About¶

NonelessDict is a wrapper around dict that will check if a value is None/empty/False, and not add the key in that case.

The class has a method set_with_strict_none_check() that can be used to set a value and check only for None values.

NonelessOrderedDict is based NonelessDict and OrderedDict, so the order of key insertion is preserved.
