delete Items from Json File that doesn't have keys ~ Python

I have a JSON file and would like to remove a certain book

[
  {
    "title": "How to love",
    "author": "vagabondage3",
    "isbn": 9832,
    "genre": "Comedy",
    "numofcopies": 2
  },
  {
    "title": "How to eat",
    "author": "belabor",
    "isbn": 2345,
    "genre": "Documentary",
    "numofcopies": 3
  },
  {
    "title": "hwo",
    "author": "TafaTIC",
    "isbn": 19,
    "genre": "Comedy",
    "numofcopies": 9
  }
]

Part to remove

{
    "title": "hwo",
    "author": "TafaTIC",
    "isbn": 19,
    "genre": "Comedy",
    "numofcopies": 9
  }

the json file should look like this in the end

[
  {
    "title": "How to love",
    "author": "vagabondage3",
    "isbn": 9832,
    "genre": "Comedy",
    "numofcopies": 2
  },
  {
    "title": "How to eat",
    "author": "belabor",
    "isbn": 2345,
    "genre": "Documentary",
    "numofcopies": 3
  }
]

    In the end it depends how you identify which one you want to delete. If you want to delete by index, you could try this:

    json_data.pop(2)

    Or you could just iterate with a condition:

    json_data = [item for item in json_data if item['title'] != 'hwo']

    Or, You can use pop() method:
