Python Python Basics (2015) Python Data Types String Formatting

I'm not sure why this isn't working.

The question says to add the .format() function again to the subject variable, am I missing something?

strings.py
name = "Tyler"

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

Part 1: name = "Godzilla" subject = "Treehouse loves {}" subject.format(name)

Part 2: name = "Tyler" subject = "Treehouse loves {}".format(name)

Hi Tyler,

In real life coding speaking mistakes in a string are no problem and won't affect your code one way or another. But for these challenges spelling mistakes can be very frustrating.

I've worked and reworked my code on here only to find I had it right the first time but just had a spelling mistake.

Your code is correct. You just have a spelling mistake.

Your string should read "Treehouse loves {}." not lives.

Hey Russell, for some reason, it still isn't working with the corrected spelling error. When I run the code through the treehouse editor I get this error:

Be sure to use the {} placeholder and the .format() method.

Not sure if it's a bug, or if I just don't have the right code! Thanks!

The way format works is you need to include what you want to add in the parentheses of the format that you want inside the {} in the string. The more {} you have in the string the more arguments you need to add to your format().

In this case you want to put your name inside the {} so you need to put either the string 'Tyler' or a variable assigned the name 'Tyler' in the parentheses of the format()

The challenge also stated to create a variable named subject to hold the string.

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

It worked! Thanks Russell!
