Chapter: Days 40-42: JSON in Python
Lecture: Inspecting JSON schema
0:00 Okay, so to start we're going to look at a basic example of JSON output or JSON schema. Okay so it is pretty complex at times,
0:11 especially when it starts getting really deep. So just look at this basic example to understand it.
0:18 So from Python perspective, it looks pretty simple for now. This is a really basic one again and it's about a sort of person object
0:26 so you've got a title of a person. You got the type, it's an object. And then what are the properties of that?
0:32 Well there is a first name, a last name, an age, a description, and so on and so forth. What really gets people and gets me sometimes
0:43 with a JSON is once it's decoded in Python, all of these become nested dictionaries and lists.
0:52 And it makes it quite difficult when you're writing loops and what not to try and drill down to those nested dictionaries.
1:01 So looking at this, if this was formatted like a dictionary in Python, your first level of the dictionary has the key title value person,
1:12 key type value object. Key properties but the value of properties is another dictionary and that dictionary goes all the way down to here, okay.
1:25 And within that dictionary, you then have another key called first name whose value is yet another dictionary, okay.
1:35 And then that closes off here and then you have another key whose value is yet another dictionary and so on.
1:43 When you break it down visually, it makes a lot more sense. That said, it is still a little bit of a crazy process trying to drill down, okay.
1:56 And we're going to work through that in the next couple of videos. So this is just a nice basic example of what JSON schema looks like.
2:03 So have a good look at this. Wrap your head around it and move onto the next video.
