How do I find and replace unlabeled attribute in JSON database?

Question

This is what my JSON database looks like:

{
  "name1": {
    "file": "abc"
    "delimiter": "n"
  },
  "name2": {
    "file": "def"
    "delimiter": "n"
    }
}

Pretend I want to change "name1" to "renamed". How would I do this using Python?

There isn't a thing before the name. For example, inside "name1" I have a string "abc" that's a "file". "name1" is just by itself. — John Smith, May 20 '21 at 23:34
The thing "before" it is just the variable holding the dictionary. — Barmar, May 20 '21 at 23:35

Using the following code:

dict = {
  "name1": {
    "file": "abc",
    "delimiter": "n"
  },
  "name2": {
    "file": "def",
    "delimiter": "n"
    }
}

{'name1': {'file': 'abc', 'delimiter': 'n'},
 'name2': {'file': 'def', 'delimiter': 'n'}}

Add another key using older key contents then delete it

dict["rename1"]=dict["name1"]
del dict["name1"]

{'name2': {'file': 'def', 'delimiter': 'n'},
 'rename1': {'file': 'abc', 'delimiter': 'n'}}

How can I define dict as my JSON database without copying and pasting my entire database in the Python code? – John Smith May 21 '21 at 16:36
is your JSON database mongodb ? – tdenimal May 21 '21 at 16:56
I'm not familiar with MongoDB. I'm pretty sure my JSON database is not MongoDB – John Smith May 21 '21 at 17:08

You can convert to dict and use pythonic way to change the key name

a ={
  "name1": {
    "file": "abc",
    "delimitert" : "n"
  },
  "name2": {
    "file": "def",
    "delimiter": "n"
    }
}

a['renamed'] = a.pop('name1')
