i am making a get request to an api that returns json with configuration information i want to parse this json and set all the variables in a `SystemConfiguration` object for ease of access elsewhere in my code i have code that does this, but the api doesnt always return every single possible configuation item since theyre not always relevant if i try to parse the json response to set such variables, i get `KeyError` since the json doesnt contain the key for that variable is there a way to skip over these exceptions and continue parsing the json to set the other items which were returned? and if so, can i gather the items that were skipped over so i can for example `echo` which items could not be parsed? there are almost 50 items, so i really dont want to have a monstrous try except for each and every variable
