Create Dictionary of Dictionary Python

I am trying to copy a dictionary of dictionary (person_profile) into a new dictionary of dictionary (person_info) because I am trying to merge two different dictionaries (person_profile and person_attribute into person_info) with not necessarily same length and key value. Below are my code (I changed the variable just to make it sound more simple):

for person in person_profile:
    person_info.update({ 
        person.id :
       {'name' : person.name, 'age' : person.age} 
    })

# And call person_attribute again
for person in person_attribute:
    person_info.update({ 
        person.id :
       {'occupation' : person.occupation, 'gender' : person.gender} 
    })

However above method seems to create a set instead of dictionary. I couldn't find how to do so in other articles. What is a recommended approach to this problem?

== ANSWERED

for person in person_profile:
    person_info[person.id] = {'name' : person.name, 'age' : person.age}

for person in person_attribute:
    person_info[person.id].update({
        'occupation' : person.occupation, 'gender' : person.gender
    })
