I am trying to import and combine two massive datasets as data frames in python. Using the merge() method I have managed to combine them over the common key. Now, I need to group all the rows to calculate the sum of the only numeric column and transform it into a data frame itself to use for modeling. I manage to run the groupby() statement, but I don’t manage to convert what I obtain into a usable data frame.
