Actualy, there is an issue with signature. sendTransaction uses a while loop to do several attempts :

>>> tx = core.Transaction(amount=1234000000, recipientId="AR1LhtKphHSAPdef8vksHWaXYFxLPjDQNU")
>>> core.sendTransaction("secret", tx)
{'transactionId': '3684489509227507694', 'attempt': 5, 'success': True}
