Does anyone know how to format JSON like this with dict? Having trouble getting objects which are the same name to not replace each other. Does that make sense?

channels: [ { channel: 1, segments: [ { start: 10, stop: 30 }, { start: 45, stop: 60 }, { start: 65, stop: 75 } ] } , { channel: 2, segments: [ { start: 35, stop: 45 }, { start: 65, stop: 75 } ] } ]
