I have a dataframe with columns being date time every 30min or sometime every 10 min. There are missing data and dates for few days. I'd like to fill missing data with zero or NaN with same time frequency. How to do it?
I found below similar question. But difference of my question is time frequency. I'd like to keep using same 30 minutes rather than using period_range for daily data filling.
sometimes, my data has 10 min time frequency. Basically I'd like to fill missing dates with same existing time frequency.
pandas fill missing dates in time series
I am pasting some data here for your reference.
