Does anyone know how I retrieve two pairs from a dictionary 
I'm trying to present data in a more compact format

```
a = {1:'item 1', 2:'item 2', 3:'item 3', 4:'item 4' }
for i,j,k,l in a:
    print i, ' - ' ,j , ' , ' ,k, ' - ' ,l

```

> 
> 1 - item 1 , 2 - item 2
> 
> 
> 3 - item 3 , 4 - item 4
> 
> 
> 

edit - sorry ment it to look like above
