Dict[str, str] means the key type and value type should both be strings,Indeed, I know that much, list[dict[str, str]] is what is getting passed in in this particular invocation of run_rw_queries(). For what it's worth here's the signature of that function: def run_rw_queries ( link_obj:_TLnkObj=None, queries:list[dict[str, str | list | dict[str, Any]]]=None, end_tx:bool=False, return_data:bool=None, get_col_idx:bool=False, verbose:bool=False ) -> tuple[list[dbapi.extras.DictRow], dict[str, int] | None]: Given that I would have thought that passing in list[dict[str, str]] for "queries" ought to be type safe. Mypy indicates otherwise which I am not grokking as to why.
ah... didn't grok what you were asking, sorry - ignore my attempt then. So you are passing something that has been typed more narrowly than the function parameter. Can you use a TypeGuard here?
