Hi Abo,

Yes your code will work fine in the Python shell and is a perfectly legitimate way of doing things, but the problem is you are going a bit out of bounds with what the challenge is asking.

First, you originally defined your name as "{}" in task 1.

So when the challenge checker is looking for your concatenated string in task 2, it is expecting to find "Treehouse loves {}".

But by using the .format() method, you've now substituted something different for your name. So now the challenge will find "Treehouse loves khaled" and won't pass because name is still defined as "{}".

Also, you don't need to print(subject) in the challenge. It is just looking for the subject variable to be defined.

Good luck.
