Problem with concatenating two dataframes

OK. That fixed the problem, however, I see that they are concatenated vertically. How can I change that to horizontal? The printed dictionary in the end looks like


{'dummy':     Value
M1      0
M2      0
M3      0, 'K1':    Value
0     10
1      5
2     10
6      2
7      2
8      2, 'K2':    Value
3     20
4     10
5     15}



For K1, there should be three rows and two columns labeled as Value.
