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

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
  }
]

I honestly saw a similar example but I can't understand it can you explain please how it was done thanks in advance <3

CodePudding user response：

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']

CodePudding user response：

You can do it in multiple ways: You can use del operator to remove a certain book by index:

del data_json[2]

Or, You can use pop() method:

data_json.pop(2)
