OK, now use .format() on the string "Treehouse loves {}"....
.format()
is a string method, which means it needs to operate directly on a string or a variable pointing to a string:
"Treehouse loves {}".format()
to put your name into the placeholder.
The placeholder, also called a replacement field, is marked by the curly brackets {}. The arguments to the format
method are used, in order, to fill in each replacement field. If more than one, the arguments are separated by a comma.
"Treehouse loves {}".format(name)
Assign this to the variable subject (so start with subject =).
The format
method takes a string and returns a new string. To save this new string, it needs to be assigned to a variable. Do this by prepending the code statement above with subject =.
Post back if you need more help. Good luck!!
