Convert python3 JSON to command line string

Question

I have a JSON file that looks like this:

{
    "options": {
        "--singleseed": "Eugene Ionesco",
        "--booktitle": "Rhinoceros"
    }
}

I am loading it via

with open('/tmp/pagekicker/test.json') as json_data:
     d = json.load(json_data)
     s = str(d)

I now want to convert this to the following string:

--singleseed "Eugene Ionesco" --booktitle "Rhinoceros"

How can I do this?

Iterate over the dictionary. Build a string

data = {
    "options": {
        "--singleseed": "Eugene Ionesco",
        "--booktitle": "Rhinoceros"
    }
}

s = ' '.join( '{} "{}"'.format(k, v) for k,v in data['options'].items() )

print(s)  # --singleseed "Eugene Ionesco" --booktitle "Rhinoceros"

This does not seem to produce the quotes around the values, e.g., "Eugene Ionesco", which are important. ' with open('/tmp/pagekicker/test.json') as json_data: d = json.load(json_data) s = "" for k,v in d['options'].items(): s += (2*"{} ").format(k, v) print(s) cli = commandpath + ' ' + s print('cli will be ' + cli) args = shlex.split(cli) print(args) ' produces --booktitle Rhinoceros --singleseed Eugene Ionesco
