You can use dict comprehension, just change () to {}.

>>> for_patient_type = {37: u'Test', 79: u'Real', 80: u'Real', 81: u'Real', 83: u'Real', 84: u'Real', 91: u'Real', 93: u'Real'}
>>> {k:v for k,v in for_patient_type.iteritems() if v == 'Real'}                                                                                               
{79: u'Real', 80: u'Real', 81: u'Real', 83: u'Real', 84: u'Real', 91: u'Real', 93: u'Real'}                                                                   
>>>
