I have been trying to concatenate two MultiIndex together, but for some reason it has not worked out yet...
import numpy as np
import pandas as pd
df = pd.DataFrame([[1,1,0,0,4],
[1,1,1,0,8],
[1,1,2,0,6],
[2,1,0,0,4],
[2,1,1,0,3]], columns=['a', 'b', 'c', 'd', 'e']
df2 = pd.DataFrame([[1,1,0,2,4],
[2,1,1,2,3]], columns=['a', 'b', 'c', 'd', 'e']
df = df.set_index(['a', 'b', 'c'])
df2 = df2.set_index(['a', 'b', 'c'])
df = pd.concat([df,df2], axis=1, join='inner')
This is the way I tried to do it and I really thought this should work. Can anyone maybe help to figure out how to combine these two in order to just get the rows where columns a, b, and c match.
The result I'm looking for:
d_x e_x d_y e_y
a b c
1 1 0 0 4 2 4
2 1 1 0 3 2 3
