How to append rows to a Pandas dataframe, and have it turn multiple overlapping cells (with the same index) into a single value, instead of a series?
You weren't very clear guy. If you want to resolve the duplicated indexes problem, probably the pd.Dataframe.reset_index() method will be enough. But, if you have duplicate rows when you concat the Dataframes, just use the pd.DataFrame.drop_duplicates() method. Else, share a bit of your code with or be clearer.
I am appending different dataframes to make one set. Occasionally, some values have the same index, so it stores the value as a series. Is there a quick way within Pandas to just overwrite the value instead of storing all the values as a series?
