Looping over lists

[Tommy Grav]

I have a list:

   a = [1., 2., 3., 4., 5.]

I want to loop over a and then
loop over the elements in a
that is to the right of the current
element of the first loop

In C this would be equivalent to:

for(i = 0; i < n; i++) {
    for(j=i+1; j < n; j++) {
	print a[i], a[j]

and should yield:
    1.   2.
    1.   3.
    1.   4.
    1.   5.
    2.   3.
    2.   4.
    2.   5.
    3.   4.
    3.   5.
    4.   5.

Can anyone help me with the right approach for this
in python?

Cheers
