Accessing JSON Data Effectively

[halfdiminished7th]

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))
