Efficiently joining two dataframes based on multiple levels of a multiindex Ask ion Asked 9 years 6 months ago Modified 1 year 9 months ago Viewed 40k times 33 I frequently have a dataframe with a large multiindex and a secondary DataFrame with a MultiIndex that is a subset of the larger one Python Efficiently Joining Two Dataframes Based On Multiple Levels . To merge by multiple keys you just need to pass the keys in a list to pd merge gt gt gt pd merge a b on A B A B value1 value2 0 1 1 23 0 10 1 1 2 34 0 20 2 2 1 2342 0 13 3 2 2 333 0 33 In fact the default for pd merge is to use the intersection of the two DataFrames column labels so pd merge a b would work equally well in this case Join DataFrames by a matching key I m trying to join two DataFrames that has a matching key Currently I ve tried with all three possible methods df merge df join df concat but with no luck
