Answer 1

First of all, you likely don't want to use print. It doesn't return anything, so use a conventional for loop if you just want to print out stuff. What you are looking for is:

>>> list1 = (1,2,3,4)
>>> list2 = [(i, i*2) for i in list1] # Notice the braces around both items
>>> print(list2)
[(1, 2), (2, 4), (3, 6), (4, 8)]
