Populating an array dynamically - zxcv101 - May-17-2022 Hi guys - am new to Python, so if my questions seem basic, pls bear with me. I have a script which returns rows of data in this format : 20220517 09:10:00 147 20220517 09:20:00 147 20220517 09:30:00 148 20220517 09:40:00 148 20220517 09:50:00 145 I get this output with the following bit of code : class IBapi(EWrapper, EClient): def __init__(self): EClient.__init__(self, self) def historicalData(self, reqId, bar): print(f'{bar.date} {round(bar.close)}') I want to store this data in an array (3 columns and not sure how many rows there will be). FYI, the first column is the date (2022-May-17), the second is the time, and the third is the price. What is the best way to do this in Python? Cheers RE: Populating an array dynamically - deanhystad - May-17-2022 Pandas. It has something called a Dataframe that works very well with columnar data. |
