That video thing You must have already added to the dictionary before.

But if the problem is that it is not in the same order, then dont worry about it. Dictionaries do not have any paticular order in their keys. They kind of just float there freely. Kenneth is going to repeat that several times during dictionary part of that course.

By the way good luck!!! I'm in a similar place in that course. Wait till You get to that second to last challenge.

Hi Craigs, I've copied your two dictionaries into my Python and this is what I've found:

d1 = {'title': 'python collection', 'teacher': {'first_name': 'kenneth', 'last_name': 'love'}}      
d2 = {'teacher' : {'last_name' : 'love', 'first_name', : 'kenneth'},'title' : 'python collection' , 'video' : 22}

The second one has a typo, as you've entered it up above. Correcting for that typo, I then run these commands:

len(d1)   # length is 2
len(d2)  # length is 3

So those are some differences, in case that helps.

Where are your '' or "" on 22?
