using + sign with .format

The following code has been presented as a solution at this step but it has not worked for me.

name = "Krisna" subject = "Treehouse loves {}".format(name)

I get the error: You need to use a + to combine the string and name.

The video covered using combining strings and .format but not using + with .format.

Just to add to Steven's answer: You said "The video covered using combining strings and .format but not using + with .format."

You don't need to use + with .format to combine strings. You use either + or .format, not both. In this case, the exercise is asking you to use +.

Thanks for that clarification, Bob. Much appreciated. :)

:point_right: You would not use + with format. But you could use + instead of format.

You didn't include a link to the challenge, but based on the error message it appears that they want you to combine the strings using concatenation, which would involved the + operator. You would not use format or include a {} placeholder in the literal string.

Your solution using format does indeed accomplish the same result, but not in the way the challenge is expecting.
