Parsing Firebase JSON with Python

问题

I'm working with the following JSON structures

{
    "-L6Tr0Wl5fuG3tDgUPCa": {
        "List": "{'x': [0.02245, 0.02196], 'y': [0.96941, 0.97014], 'z': [0.05344, 0.05368]}",
        "Index": "17361"
    },
    "-L6Tr4j05NV6BJKcaRSe": {
        "List": "{'x': [0.03196, 0.01537], 'y': [0.96795, 0.96966], 'z': [0.05051, 0.04929]}",
        "Index": "17362"
    }
}

The name of each entry is random (e.g. L6Tr0Wl5fuG3tDgUPCa) that is generated by firebase whenever we push a new entry. What is the best way to parse and iterate through each entry of such a JSON file in python?

The file is huge with a couple of thousands of such entries.

I've never done Python before, but this seems to work in https://www.python.org/shell/:

import json
data = {
    "-L6Tr0Wl5fuG3tDgUPCa": {
        "List": "{'x': [0.02245, 0.02196], 'y': [0.96941, 0.97014], 'z': [0.05344, 0.05368]}",
        "Index": "17361"
    },
    "-L6Tr4j05NV6BJKcaRSe": {
        "List": "{'x': [0.03196, 0.01537], 'y': [0.96795, 0.96966], 'z': [0.05051, 0.04929]}",
        "Index": "17362"
    }
}

for key in data:
  print(key, data[key])
