I am new to list comprehension, and I'd like to do something with tuples. So this is the problem:
Given two vectors l1 and l2, I wish to combine them into tuples. Then I'd like to multiply them before summing all of them up.
So for example, if i have l1 = [1,2,3] and l2 = [4,5,6], I'd like to combine them with zip function into [(1,4),(2,5),(3,6)].
After this, I want to multiply and add 1 to the tuples. So it will be [(1*4)+1,(2*5)+1,(3*5)+1], giving [4,11,16]
After that I want to sum the list up into 4+11+16 which should give 31.
I've learnt tuple(map(operator.add, a, b)) before which can add up the tupples. But since now I need to do one more calculation, I have no idea how to get started. It will be good if it can be done in a single line with list comprehension. Anyone got an idea?
