How to delete sub keys ( and underlying key/pairs )from a dictionary

The_CLog

How do I go about deleting specific sub keys ( and underlying key/pairs )from a dictionary. For example:

 {
	"Key A": {
		"1": {
			"question": "question",
			"answer": "answer"
		},
	"Key B": {
		"1": {
			"question": "question",
			"answer": "answer"
		}
	},
	"Key C": {
		"1": {
			"question": "question",
			"answer": "answer"
		},
		"2": {
			"ActualQuestion": "What .. this?",
			"Answer": "New Question...swer"
		}
	}
}

Let's say I want to delete rec "1" the Key C:

"1": {
			"question": "question",
			"answer": "answer"
		},

I thought maybe :

var question_group = data["Key C"]
question_group.erase("1")

but this doesn't seem to work. I don't need to iterate through the dictionary, I want to pull up that record and then have the option to delete it.

Thanks in advance

Stupid of me :# , it works but I wasn't saving the file after so it didn't update. A:though I would like to know before I go there will it still work if I'm on that record before deleting? Or would I need to flag the record for deletion and then go back to main screen or another record?
