Given the example dataframe:

```
   Field Value
0    a     A
1    b     1
2    c     3
3    d     2 
4    e     3
5    f     1
...

```

Where the Field column repeats in groups of 6 rows (a->f). How can I unstack the dataframe using pandas?

i.e.

```
  a b c d e f
0 A 1 3 2 3 1
1 ...
.
.
.

```

I could naively do this by iteration and appending to a new dataframe. Any helpful functions to do this in pandas?

```
example_df = pd.DataFrame({'Field':['a','b','c','d','e','f'], 'Value':[1,2,3,4,5,6]})

```
