Working with Known JSON Schemas - Lab

Introduction

In this lab, you'll practice working with JSON files whose schema you know beforehand.

Objectives

You will be able to:

  • Use the JSON module to load and parse JSON documents
  • Write data to predefined JSON schemas
  • Convert JSON to a pandas dataframe

Reading a JSON Schema

Here's the JSON schema provided for a section of the NY Times API:

or a fully expanded view:

You can more about the documentation here.

You can see that the master structure is a dictionary and has a key named 'response'. This is also a dictionary and has two keys: 'data' and 'meta'. As you continue to examine the schema hierarchy, you'll notice the vast majority, in this case, are dictionaries.

Loading the Data File

Start by importing the json file. The sample response from the api is stored in a file ny_times_movies.json

#Your code here

Loading Specific Data

Create a DataFrame of the major data container within the json file, listed under the 'results' heading in the schema above.

#Your code here

How many unique critics are there?

#Your code here

Create a new column for the review's url. Title the column 'review_url'

#Your code here

How many results are in the file?

Summary

Well done! Here you continued to gather practice extracting data from JSON files and transforming them into our standard tool of Pandas DataFrames.
