Hi Amit, This is fairly inefficient. Because strings in python are immutable this approach causes a new string to be created every iteration. While it may not be an issue with just 3 strings, it is much better to create your list and use "".join() to create the concatenation after the list is complete. When you get used to it, it's a bit more concise and readable, also.
