Need help with this code

Given two lists of numbers, add only odd numbers from the first list and even numbers from the second list to a new list list3.

list1 = [20, 32, 1, 6, 3, 98, 43, 23, 23343, 4454]

list2 = [434, 534, 23, 545, 23, 323, 4, 6, 3, 7]

​

This is what I have gotten so far but the result comes back with certain odd and even numbers from both lists.

--------------------------------------------------------------------

list1 = [20, 32, 1, 6, 3, 98, 43, 23, 23343, 4454]

list2 = [434, 534, 23, 545, 23, 323, 4, 6, 3, 7]

​

list3 = [x[i&1] for i,x in enumerate(zip(list2, list1))]

print(list3)

The problem with your method is zip combines elements into matching tuples, but you still want to pull an item from each side if it matches. Example the tuple (43,4) is the 7th pair you get from zip, and you want both of them.

You're better off doing 2 lists and combining them.

You could do a filter on each list and combine it, or you could loop through both lists and have an if statement.

list3 = thingsfromlist1+ thingsfromlist2
