Demo

In this demo, you’ll write code to write and read JSON files, just as you did for text and CSV files.

Writing To a JSON File

Start by writing a JSON file to your computer’s filesystem so you’ll have one to read later.

Reading From a JSON File

Now, read the JSON file you just created. Run the following in a new code cell:

with open("programming-languages.json", "r") as file:
  data = json.load(file)
  print(data)
