'is there a function to get mean values of a column for every unique date in date column?
jupyter notebook screenshot showing al columns in the datasetI have an AQI(Air Quality Index) dataset for which there are various columns such as O3, SO2, PM2.5,etc and a datetime column which has timestamps in it like (20-Sep-2017 - 01:00, 20-Sep-2017 - 00:00). I want to get mean value of columns for every unique date such as O3 has several values but I want only mean for 20-Sep-2017. I've tried regex, and many other things but did not get desired output.
