How to verify signature of a given transaction data?

I need to check if a transaction is valid, and that includes verifying its signature. But here’s the catch: I can’t rely on pre-made Bitcoin tools. Instead, I’ll have to write my own code using Python libraries.

transaction data:

{
  "version": 1,
  "locktime": 0,
  "vin": [
    {
      "txid": "3b7dc918e5671037effad7848727da3d3bf302b05f5ded9bec89449460473bbb",

    },
    {
      "scriptpubkey": "0014ad4cc1cc859c57477bf90d0f944360d90a3998bf",
      "scriptpubkey_asm": "OP_0 OP_PUSHBYTES_20 ad4cc1cc859c57477bf90d0f944360d90a3998bf",

}
