Hi!

So, what the format method does, is fill the placeholders "{}", with whatever you tell them to. Here is how it works.

# This next statement will assign the string "My name is Eric" to the my_name variable
my_name = "My name is {}".format("Eric") 
# This next statement does the same as the last one, but using the name variable instead of directly 
#putting my name into the statement.
name = "Eric"
my_name = "My name is {}".format(name)

So, following that. What you want to do in this task is use the name variable with the format method to assign the value subject to "Treehouse loves name"

Here it is:

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

hint: For python, "name" is not the same as "Name", so try to make use of that to organize your code.

What does "Name" do?

When the instructions say "Assign this to the variable subject", the "this" they are talking about is the result of using ".format() on the string "Treehouse loves {}" to put your name into the placeholder".

Also, be aware that calling format on a string doesn't modify the string itself, so unless you assign the result to something there's no way to tell that anything happened.

name is the variable you have previously set. In your case, you set it to 'joe', in my case, I set it to 'Eric'. Anyway...

A variable is a place in memory where you store a value.

Hope it helps.
