Intersection of two or more DataFrame columns

Question

I am trying to find the intersect of three dataframes, however the pd.intersect1d does not like to use three dataframes.

import numpy as np
imp         


        

Answer 1

You can using concat

pd.concat([df1.head(1),df2.head(1),df3.head(1)],join='inner').columns
Out[81]: Index(['C', 'D'], dtype='object')
