Access to an attribute of a class when the name is a reserved keyword- Python-CodePudding

I have a "item" object (<class 'zenpy.lib.api_objects.Comment'>) coming from an API call (JSON) like this:

{
"id": 1,
"type": 10,
"via": {
     "from":{
        "id": "511",
        "name": "a"
     },
     "to":{
        "id": "999",
        "name": "b"
     }
   }
}

So, when I do

print(item.via.to['id'])

it works properly, but when I try to do:

print(item.via.from['id'])

I'm getting an error SyntaxError: invalid syntax on the "from". Because is a reserved keyword.

How can I access to that value? I can't change the "from" name because is coming from an API call.

Thank you.

CodePudding user response：

Peeking through the code of the API you are referencing, it looks like reserved words the convention for their classes is to prefix it with a leading _ (looking here)

So try using item.via._from, the _from is a valid identifier.

Could also be best to call the to_dict or even actual lower-level __dict__ on the object and access it by string, but I think the first should work:


x = item.via._from.id


x = item.to_dict()["via"]["from"]["id"]

# or worst case…

x = item.via.__dict__["from"].id
