Need Help with a Python Code that I put together, Wallet.dat Extractor

I have coded a wallet.dat private key extractor, that allows input of a folder directory, and all (Anyname).dat files in the entire directionary to be outputted to a file called privatekey.txt it does as expected, but it doesn't give me addresses and private keys that the bitcoin core client finds with the dat file.
Did I do something wrong, which results in incorrect privatekeys?

Tip of 0.0025 BTC for help, thanks
