Edit mutiple JSON files at once?

this is for an NFT project. I want to change the word 'Tiger' to 'Lion' in the 'name' section so it would effect all 3333 json files. Basically editing the whole range of files in one go. What piece of python code can I use to do this?

{
  "name": "Tiger Gen 0 #2",
  "description": "3333 Tigers.",
  "seller_fee_basis_points": 888,
  "image": "2.png",
  "edition": 2,
  "attributes": [
    {
      "trait_type": "background",
      "value": "blue sky"
    },
    {
      "trait_type": "accessories",
      "value": "none"
    },
    {
      "trait_type": "skin",
      "value": "god of war"
    },
    {
      "trait_type": "clothing",
      "value": "views"
    },
    {
      "trait_type": "hair",
      "value": "travis black"
    },
    {
      "trait_type": "eye",
      "value": "cyborg"
    },
    {
      "trait_type": "mouth",
      "value": "none"
    }
  ],
  "properties": {
    "files": [
      {
        "uri": "2.png",
        "type": "image/png"
      }
    ],
    "category": "image",
    "creators": [
      {
        "address": "234fjuinirino3i4no30234",
        "share": 100
      }
    ]
  }
}
