Bug 1753603

Description of problem:
On RHEL-8
# yum install openscap openscap-python3 scap-security-guide
# vim /root/get_results.py
import openscap_api

benchmark = openscap_api.xccdf.benchmark_import("/tmp/scap-results.xml")

# Print the ID to show that simple characters work
print("Title is: {0}".format(benchmark.get_id()))

# Print the results array to show that arrays also work and show the number of items to show that this is a python array
results = benchmark.get_results()
print(results)
print("Number of items: {0}".format(len(results)))

# oscap xccdf eval --results /tmp/scap-results.xml --profile xccdf_org.ssgproject.content_profile_ospp /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml

# python3 get_results.py

***************My thoughts***********************
1. It looks code is trying to retrieve value from Dictionary OSCAP for this key 
(wig Object of type 'struct xccdf_result_iterator *' at 0x7f7d310cb030>_has_more_new) and Dictionary does not have any key present.

        # It's maybe looking for "new" ?
        obj = OSCAP.__dict__.get(self.object+"_new") <<<<<<<<<
        if obj != None:
            return OSCAP_Object.new(obj(*newargs))

2. _openscap_py module is imported as shared Object.
# ls -ltr /usr/lib64/python3.6/site-packages/_openscap_py.so
-rwxr-xr-x. 1 root root 1672096 Jun 14 05:00 /usr/lib64/python3.6/site-packages/_openscap_py.so
    def _import_helper():
        from os.path import dirname
        import imp
        fp = None
        try:
            fp, pathname, description = imp.find_module('_openscap_py', [dirname(__file__)])
        except ImportError:

When I see OSCAP.__dict__ it does not contain object address rather it contains function names and built in types.
How it this dictionary created?
