}

I want to read quake.data.properties.depth[0].pacific

I have used the following ref as example, but that code could not read "pacific" attribute.

  • This seems unclear what you need. Is this a string or a dict? If it's a string, are you trying to get a dict? If you want one object to represent this entire structure, you'll need to write a class. If you just want the one property, `json.loads(s)['data']['properties']['depth'][0]['pacific']`? – ggorlen Apr 07 '20 at 18:29

  • There's no such thing as a "JSON dict". There are JSON objects, which are particular string values that can be decoded into a Python `dict`. If you already have the `dict`, and are asking how to use that to initialize an instance of some other Python class, this question has nothing to do with JSON. – chepner Apr 07 '20 at 18:31
  • @ggorlen - my apologies for not being clear. I want to convert the json string to an object and read it this way quake.data.properties.depth[0].pacific rather than reading it from a dict like you mentioned. – user1625342 Apr 07 '20 at 18:52
  • I see. You'll need a class, then. There are third party tools that let you do this, see [this thread](https://stackoverflow.com/questions/12465588/convert-a-json-schema-to-a-python-class). – ggorlen Apr 07 '20 at 18:59
