Why does this use of placeholders not work? name = "shayan" subject = "Treehouse loves {}" subject.format(name)

I get an error when I try to do this task. Am I making a very obvious mistake? (sorry newbie)

strings.py
name = "shayan"
subject = "Treehouse loves {}"
subject.format(name)

Hi Shayan,

The challenge is asking you to assign the fully formatted string into the variable subject. Your code currently assigns the template to subject, then throws out the formatted string (the '.format(). method doesn't actually change the value of the variable it's called on). So your subject variable still has the value "Treehouse loves {}" after your code runs.

Hope this helps. Elad

name = "Elad" comment = "Thanks a lot! {}".format(name)
