Compare Two Lists and Replace Items In a List by Index

[nagymusic]

I'm working on a problem in which I'd like to compare two lists of numbers:

list_a = [0, 1, 2, 3]
list_b = [4, -2, 3, -1]

Then, I'd like to create a new list_c that transforms the list_a by examining every negative number in list_b and then replaces the corresponding number in list_a (at the same index number when compared to list_b) with None.

list_c = [0, None, 2, None]

I welcome your suggestions on what would be the most efficient way to achieve this. Thank you.
