Hi@akhtar,

You can use Pandas.merge() function to merge your DataFrame. I have attached one example below for your reference.

import pandas as pd

df1 = pd.DataFrame({"HPI":[80,90,70,60],"Int_Rate":[2,1,2,3], "IND_GDP":[50,45,45,67]}, index=[2001, 2002,2003,2004])
HPI Int_Rate IND_GDP
2001 80 2 50
2002 90 1 45
2003 70 2 45
2004 60 3 67

df2 = pd.DataFrame({"HPI":[80,90,70,60],"Int_Rate":[2,1,2,3],"IND_GDP":[50,45,45,67]}, index=[2005, 2006,2007,2008])

HPI Int_Rate IND_GDP
2005 80 2 50
2006 90 1 45
2007 70 2 45
2008 60 3 67
merged= pd.merge(df1,df2,on ="HPI")

HPI Int_Rate_x IND_GDP_x Int_Rate_y IND_GDP_y
0 80 2 50 2 50
1 90 1 45 1 45
2 70 2 45 2 45
3 60 3 67 3 67
