Week4 Coding Exercise 16

#16
print("This program is written to filter out the odd elements between two lists inputs of ANY TYPE of user choices.")
print("|||||"*24)

#I am going to be demonstrating the functionality of this code by filtering out the odd colour choices of my code user and his/her anonymouus friend

#The Function Program
def destroy_elements(expected_list1,expected_list2):
    odd_element = []
    for a in range(len(expected_list1)):
        if expected_list1[a] not in expected_list2:
            odd_element.append(expected_list1[a])
    print(odd_element)


#The lines of codes below make use of list comprehension. It can also be used in the function.

#   print([odd_element.append(expected_list1[a]) for a in range(len(expected_list1)) if expected_list1[a] not in expected_list2])



#My Main Code

        print("|||||"*24)
