Working with JSON in Python

json.loads()

Convert a string containing JSON data into the native Python dictionary object. Equivalent to JSON.parse() in JavaScript.

Will error if the input string is not properly formatted JSON. This will be json.JSONDecodeError, a subclass of the ValueError exception

json.dumps()

Take a JSON-formatted dictionary and convert it into a string. The reverse of json.loads() and equivalent to JSON.stringify() in JavaScript.

json.dump()

Not to be confused with the above. Output a Python dictionary as JSON, for instance to create a .json file:

data = { "key": "value"}
with open("some/directory/output.json", "w") as f:
    json.dump(data, f, indent=4)
