What is the method for including an item in a Dictionary?

I encountered an issue with a nested dictionary in a Json file. Here is the current content of the file (highscore_history.txt):

{
    "Highscores": {
        "0highscore": 2
    }
}

My goal is to add a new entry into the nested dictionary...

with open("highscore_history.txt", "w") as Highscore_history_txt:
    highscore_history["Highscores"].update({f"{last_element_of_the_history}highscore": main_game.current_highscore[-1]})
    json.dump(highscore_history["Highscores"], Highscore_history_txt, indent =4)
    saved_highscores = {f"{last_element_of_the_history} highscore": main_game.current_highscore[-1]}

However, when I implement this code snippet, the new key-value pair appears outside the second dictionary:

{
    "Highscores": {
        "0highscore": 2
    },
    "1highscore": 0,
}

I am seeking guidance on how to ensure that the new entry is properly added inside the nested dictionary.

Update

Here is a quick example demonstrating how to add new data to a JSON file while maintaining the same structure.

Original JSON:

{
  "Highscores": {
    "0highscore": 2
  }
}

Code snippet:

import json

def write_json(data):
    with open("data.json", "w") as f:
        json.dump(data, f, indent=2)


with open('data.json') as json_file:
    data = json.load(json_file)
        
data['Highscores']['1highscore'] = 0
write_json(data)

Updated JSON:

{
  "Highscores": {
    "0highscore": 2,
    "1highscore": 0
  }
}
