Description:
 def getLogs(self, argument_filters=None, fromBlock=None, toBlock=None, blockHash=None):
 """Get events for this contract instance using eth_getLogs API. This is a stateless method, as opposed to createFilter. It can be safely called against nodes which do not provide eth_newFilter API, like Infura nodes. If there are many events, like ``Transfer`` events for a popular token, the Ethereum node might be overloaded and timeout on the underlying JSON-RPC call. Example - how to get all ERC-20 token transactions for the latest 10 blocks: .. code-block:: python from = max(mycontract.web3.eth.blockNumber - 10, 1) to = mycontract.web3.eth.blockNumber events = mycontract.events.Transfer.getLogs(fromBlock=from, toBlock=to) for e in events: print(e["args"]["from"], e["args"]["to"], e["args"]["value"]) The returned processed log values will look like: .. code-block:: python ( AttributeDict({ 'args': AttributeDict({}), 'event': 'LogNoArguments', 'logIndex': 0, 'transactionIndex': 0, 'address': '0xF2E246BB76DF876Cef8b38ae84130F4F55De395b', 'blockNumber': 3 }), ) See also: :func:`web3.middleware.filter.local_filter_middleware`. :param argument_filters: :param fromBlock: block number or "latest", defaults to "latest" :param toBlock: block number or "latest". Defaults to "latest" :param blockHash: block hash. blockHash cannot be set at the same time as fromBlock or toBlock :yield: Tuple of :class:`AttributeDict` instances """
