Answer 1

Well, that's not valid json, so the json module won't help you to write that data. But you can do this:

import json

with open('es_hosts.json', 'w') as fp:
    data = ['a', 'b', 'c']
    fp.write(json.dumps(','.join(data)).replace('"', ''))

That's because you asked for json, but since that's not json, this should suffice:

with open('es_hosts.json', 'w') as fp:
    data = ['a', 'b', 'c']
    fp.write(','.join(data))
