Not sure what's wrong with my format statement

I'm not sure what's wrong with my format statement: name = "{}.format(bill)" subject = "Treehouse loves {}.format(name)"

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

You may have overthought it with the name variable.

name = "Bill"

and then

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

Using {} in our subject variable is simply setting up a placeholder for our name variable.

Hope this helps :)

Hi there, format is a method (internal function) of the String class, so to use it, you put .format() on the end of the string you want to use it with, not inside it. At the moment your code just tells python to ignore it as part of the string. You need to add it after the string, then tell it what to put in the string, so

name = "{}".format("bill")

Would work.

The reason is we have our string:

"Hello"

So to add to it we'll use the .format() method:

"Hello".format()

First we give our format function a clue where to insert something:

"Hello {}".format()

Then we tell it what to insert, in this case a string

"Hello {}".format("World")
