# Step 1: Define two lists with some common elements
list1 = [1, 2, 3, 4]
list2 = [3, 4, 5, 6]

# Step 2: Merge both lists into one
merged_list = list1 + list2

# Step 3: Remove the common elements from the merged list
unique_elements = [item for item in merged_list if merged_list.count(item) == 1]

# Step 4: Display the result
print("List with merged unique elements:", unique_elements)
