How to group variables & check correlation of group variables wrt single variable

[SriRajesh]

Var1   Var2    Var3  
6       4.6    5
8       5.9    6 
14      8.2    8 
6       1      2.6 
7       2.6    9.3  
9       11.2   0.2 
4       5      2.9
6       3      6
2       1      3

I want check correlation of (1) Var1,Var2,Var3 & (2)I want to group Var1&Var3=Var4 and check correlation of Var1,Var2,Var3,Var4

I want correlation table as below:

     Var1  Var2  Var3
Var1
Var2
Var3

             Var1    Var2    Var3  Var4(Var1$Var3)
Var1
Var2
Var3
Var4(Var1$Var3)

What have you tried? We are glad to help, but we are not going to do it for you. Please, post your code in python tags, full traceback if you get any exceptions - in error tags and ask specific questions.

I tried as Below:
My input matrix is stored in dataframe

import pandas as pd
df = pd.DataFrame({'Var1': [6,8,14,6,7,9,4,6,2], 'Var2': [4.6,5.9,8.2,1,2.6,11.2,5,3,1],'Var3': [5,6,8,2.6,9.3,0.2,2.9,8,3]})
pd.scatter_matrix(df, alpha = 0.3, figsize = (14,8), diagonal = 'kde');

but I don't know how group Var4(i.e., Var1&Var3), and re-do above process
