To join 2 pandas dataframes by column, using their indices as the join key, you can do this: And if you want to join multiple DataFrames, Series, or a mixture of them, by their index, just put them in a list, e.g.,: See the pandas docs for DataFrame.join(). I think Pandas is the best way to go. The second column is instead renamed to startup_select selects cells, rows or columns at initialization by using a tuple e.g. Would salt mines, lakes or flats be reasonably found in high, snowy elevations?
