Currently I do leave the data I extract the keys out as a full path.
If I use pprint as suggested I get close.
['glossary'],
['glossary', 'title'],
['glossary', 'GlossDiv'],
['glossary', 'GlossDiv', 'title'],
['glossary', 'GlossDiv', 'GlossList'],
['glossary', 'GlossDiv', 'GlossList', 'GlossEntry'],
['glossary', 'GlossDiv', 'GlossList', 'GlossEntry', 'ID'],
['glossary', 'GlossDiv', 'GlossList', 'GlossEntry', 'SortAs'],
['glossary', 'GlossDiv', 'GlossList', 'GlossEntry', 'GlossTerm'],
['glossary', 'GlossDiv', 'GlossList', 'GlossEntry', 'Acronym'],
...]
But to select elements from the json I need the format json['elem1']['elem2] .
I want to be able to get any json in future and parse it into my function and
return a list of all json key elements.
Then using this cool answer on SO https://stackoverflow.com/a/14692747/461887
from functools import reduce # forward compatibility for Python 3
import operator
def getFromDict(dataDict, mapList):
return reduce(operator.getitem, mapList, dataDict)
def setInDict(dataDict, mapList, value):
getFromDict(dataDict, mapList[:-1])[mapList[-1]] = value
Then get the values from the keys
>>> getFromDict(dataDict, ["a", "r"])
1
That would mean I could using my function if I get it write be able to feed it
any json, get all the full paths nicely printed and then feed it back to the SO
formula and get the values.
It would essentially self process itself and let me get a summary of all keys
and their data.
Thanks
