how to convert two dataframes e.g.:

```py
df1=pd.DataFrame({'A': [1, 2,3], 'B': [10, 20,30]})
df2=pd.DataFrame({'A': [11, 22,33], 'B': [110, 220, 330]})

```

into

```
     A       B
0   (1, 11) (10, 110)
1   (2, 22) (20, 220)
2   (3, 33) (30, 330)

```

I'm trying to find a pandas function instead of using a loop. This is just a dummy example and the original dataframes have many columns
