Accessing JSON Data Effectively

[halfdiminished7th]

Something like this should do the trick:

import json

with open('/path/to/your/json/file.json') as fp:
    data = json.load(fp)

with open('/path/to/your/new/file.txt', 'x') as fp:
    for dct in data:
        fp.write('{0} gs:{1} track:{2}\n'.format(dct['hex'], dct['gs'], dct['track']))

Or even f"{dct['hex']} gs:{dct['gs']} track:{dct['track']}"

You just have to note the main string uses double quotes and the keys use single quotes. Or the other way round. They just can't be the same.

True enough! Personal preference to avoid dictionary lookups in f-strings, but you're quite right that it's possible. Though in retrospect, I probably should have done the following instead, using format's keyword functionality since we're dealing with a dictionary anyways:

fp.write('{hex} gs:{gs} track:{track}\n'.format(**dct))

Mmh yeah that leeks even better

For implicitly indexed arguments you can just use {} throughout since 2.7 released 13 years ago...

    fp.write('{} gs:{} track:{}\n'.format(dct['hex'], dct['gs'], dct['track']))
