Problem is this, take two lists, say for example these two: a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89] b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] And write a program that returns a list that contains only the elements that are common between the lists (without duplicates). Make sure your program works on two lists of different sizes. Here's my code: a = [1, 1, 2, 2, 3, 5, 8, 13, 21, 34, 55, 89] b = [1, 2, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] c = [] for i in a: if i in b and i not in c: c.append() print(c) My output is still giving me duplicates despite the 'i not in c' statement. why is this? I'm sure its blatantly obvious, I just cant see it! Continue reading...
