Writing clean code: Nested For/If/Elif in Pyramid

I have been trying to cleanly write a for loop that includes conditionals to print 1. user results and 2. if user results do not exist, print pending assessments (tasks).

I'm currently taking this thing for a loop without end result (meaning I cannot figure this out). Essentially the goal is: So a user can know what they have completed and what remains to be done.

Currently all_assessments prints out a list of all the existing assessment names and text.

all_assessments = [<Assessment(name='Becoming a Leader', text='better decisions')>, <Assessment(name='Good work', text='working on these skills')>, <Assessment(name='Teaching NTS', text='Series 1.1')>]

while all_results prints out all results of every user in a list. Shown here:

all_results [<Assessment_Result(owner='<User(username ='baseball', password='...', firstname ='Jenny', lastname ='Jen', email='dance@aol.com')>', assessment='<Assessment(name='Becoming a Leader', text='better decisions')>')>, <Assessment_Result(owner='<User(username ='donald', password='...', firstname ='Drew', lastname ='James', email='cool@gmail.com')>', assessment='<Assessment(name='Good work', text='working on these skills')>')>]

and finally, user_results prints results found by username (which is based on whomever is logged in).

retrieved by username: [<Assessment_Result(owner='<User(username ='dorisday', password='..', firstname ='Doris', lastname ='Day', email='dorisday@gmail.com')>', assessment='<Assessment(name='Becoming a Leader', text='better decisions')>')>, <Assessment_Result(owner='<User(username ='dorisday', password='..', firstname ='Doris', lastname ='Day', email='dorisday@gmail.com')>', assessment='<Assessment(name='Good work', text='working on these skills')>')>]

        owner = authenticated_userid(request)
        print 'login owner', owner
        if owner is None:
            raise HTTPForbidden()
        all_assessments = api.retrieve_assessments()
        print 'these are all the assessments:', all_assessments
        print 'and type:', type(all_assessments)
        all_results = api.retrieve_assessment_results() # all the assessment results in a list

        user_results = api.retrieve_assessment_byusername(owner) #all completed results of user
        for x in all_assessments:
            print 'all assessments', x
        for a in user_results:
            #print 'Done ', a.assessment # seperates each result (assessment object)
            done = a.assessment.name
            if done is not None: #length greater than zero
                print 'done', done
            else:
                print 'pending', x #doesn't work: supposed to print remaining assessments

        return {'assessments': all_assessments, 'assessment_results': all_results, 'loggedin': owner, 'user_results': user_results}
