Problem

Currently, the Python SDK implementation of TransactionGetReceiptQuery supports only the following fields:

self.transaction_id: Optional[TransactionId] = transaction_id
self.include_children:bool = False
self._frozen: bool = False

However, it does not expose support for requesting duplicate transaction receipts, which are already supported at the protocol level (Protobuff) and in other SDKs (e.g., JavaScript).

Expected Behavior:

The query should allow user to optionally request receipts for duplicate transaction. Similar as implemented for child receipt in PR #1114.

Eg:

query = (
    TransactionGetReceiptQuery()
    .set_transaction_id(tx_id)
    .set_include_duplicates(True) #True/False
)

Solution

• Add support for an include_duplicates field to TransactionGetReceiptQuery class.
• Create a setter method set_include_duplicates(bool).
• Update TransactionReceipt class to include the duplicates field.
• Add a function to process the duplicates receipts form the TransactionGetReceiptQuery response

# Suggested to created a single method to process  both children and duplicate receipt
# Example func that convert the child/duplicates receipts to TransactionReceipt list and then return
def _map_receipt_list(self, proto_receipts: List[transaction_receipt_pb2.TransactionReceipt]) -> List["TransactionReceipt"]:
        receipts: List[TransactionReceipt] = []
        for receipt in proto_receipts:
            receipts.append(TransactionReceipt._from_proto(receipt, self.transaction_id))
        
        return receipts

• Update _make_request() function of TransactionGetReceiptQuery to include_duplicates field while creating the proto
• Create a example for demonstrating and using these new field
• Update/Add unit and integration test for the changes

Alternatives

• Additionally add @property for getting _duplicates from the TransactionReceipt
