I use python/django, and I have a tuple of tuples (or list of tuples. doesn't really matter), basically it's the output of an SQL query. I print it like this:

If I have 

```
output= [(a1,b1,c1,d1), (a2,b2,c2,d2), ...] 

```

So I'll do: 

```
for a,b,c,d in output:
  ...

```

now the thing is that sometimes I select a lot of columns and I don't want to print them all.
Can I unpack only the values that I need. or I'm limited because of the order of the tuples?  

i.e can I do for example:

```
for a, d in output:
   ...

```

(notice,I want to skip the second and third value in the tuples)
Is that possible or I have to user indexes?

Obviously it is slightly different in django template, but the point is the same.
