From this StackOverflow answer.
prettyjson() is a Python function that allows to pretty-print JSON content with line splits and indentations.
Usage:
txt = prettyjson(obj, indent=2, maxlinelength=80)
obj- any object containing lists, dicts, tuples and basic types.indent- number of characters to indent the next level with.maxlinelength- maximum number of characters per line.
Example of rendered JSON:
{
"grid": {"port": "COM5"},
"policy": {
"movingaverage": 5,
"hysteresis": 5,
"fan1": {
"name": "fan1",
"signal": "cpu",
"mode": "auto",
"speed": 100,
"curve": [[0, 75], [65, 75], [75, 100]]
},
"fan2": {
"name": "fan2",
"signal": "gpu",
"mode": "auto",
"speed": 100,
"curve": [[0, 75], [65, 75], [75, 100]]
}
},
"signals": {
"cpu": {
"fn": "max",
"sensors": [
"/intelcpu/0, CPU Core #1", "/intelcpu/0, CPU Core #2",
"/intelcpu/0, CPU Core #3", "/intelcpu/0, CPU Core #4"
]
},
"gpu": {"fn": "max", "sensors": ["/nvidiagpu/0"]},
"sys": {"fn": "max", "sensors": ["/intelcpu/0", "/nvidiagpu/0"]}
},
"app": {

}
Various data setups are conveniently rendered:
