6if value in items:
7    items.remove(value)
8    print("Updated list:", items)
9else:
10    print("Value not found in list.")

Output

Enter list elements separated by space: 1 2 3 2
Enter value to remove: 2
Updated list: ['1', '3', '2']

What's going on

We use the list method .remove() which deletes the first matching element.
