Roibal Bot get_historic_klines function doesn't work, or does it?

Hi,

I am new to programming and Python. I was reading and checking your code piece by piece.
At save_historical_data_Roibal.py get_historic_klines function, I added a print(output_data) line at the bottom and ran the code with get_historical_klines('BTCUSDT', Client.KLINE_INTERVAL_30MINUTE, "1 Aug, 2018", "5 Aug, 2018"). Well all the parameters look fine. I was expecting to see all the klines between that period but instead nothing happens. Am I interpreting the code wrong? How should I change the code to see the klines at this period?

Thank you in advance for your assistance.
