import json: Enable json functions. The json module is standard available (no installation needed)

Read a json file and return it as dict.

import json
with open(filename) as fh:
    data = json.load(fh)

Can be used on datatypes like lists and tuples too, not on sets.

json.dumps(dict, indent=4): Convert a dict into a json string nicely structured. Indent each level with 4 spaces.
json.dump(dict, fh, indent=4): Dumps to the file opened on filehandle fh.
