Video Summary:
JSON strings look a lot like Python dictionaries. Python has a built in module "json" for working with JSON data.
Using the module we can perform a lot of operation on the JSON data.

To convert a JSON string to a python dictionary or a list, we use the "json.loads" function.

To convert a python dictionary or a list to a JSON string, we use the "json.dumps" function. To format the output string, we can use the indent keyword and that will make the JSON look nice.

To read JSON from a file, we use the json.load using the file handler of that file.

To write JSON to a file, we use the json.dump, again using the file handler of that file. Even for dump, we can pass in the indent keyword argument to make the output formatted.
