I am new to programming. I am currently learning python and I am trying to add pairs of numbers in a list. Let's say I have something like this:

a = [1, 2, 3, 4 , 5, 6]

and I am trying to add them in pairs like this:

a = [1 + 2, 3 + 4, 5 + 6]

Also, the list will always have an even number of elements.I can't wrap my mind around the problem. Please Help.

What if the input array/list is has odd number of elements? – Azher Aleem Jul 24 '20 at 13:33
``[x + y for x,y in zip(a[1::2] , a[0::2])]`` – sushanth Jul 24 '20 at 13:35
`it = iter(a); [x+y for x,y in zip(it,it)]` – Chris_Rands Jul 24 '20 at 13:36
