How to get the tokenids of certain ERC721 tokens for a adress? using Web3py

Question

A known way:

1. call balanceOf to get the number of tokens owned by the address call
2. Call tokenOfOwnerByIndex in a loop to get each owned token ID.

But what I'm very confused about is what to do when the ERC721 contract has not included tokenOfOwnerByIndex function

Answer 1

tokenOfOwnerByIndex is what most token will provide for you to enumerate in, but you could use Transfer event on that contract to do that also
