//Find Element Not In List #

Today, I have to write a Python program that prints the elements of list A that are not in list B as a list.

For example, if list A = [1, 2, 3] and list B = [1, 2], then the output will be [3].

My solution is to go through all elements in list A and for each element I check if it exist in list B. If it doesn’t I will put it all in the output list.

HERE IS THE CODE:

a = [1,2]
b = [1, 2]

output = []

for i in a:
    #print(i)
    if i not in b:
        output.append(i)

print(output)
