I am using the `{}` placeholder and the `.format()` method. but it will not work. Where am I wrong?

Question

I works in idle
```strings.py
name="niels"
subject="Treehouse loves {}"
subject.format(name)
```

To provide you with a why your code didn't work...
Both snippets of code are correct in syntax, but the first one fails the challenge because it is not what the challenge is asking for. The instructions specifically say to apply the format() to the string, but you applied it to the variable. So, while this technically works, it isn't what is asked, and it can also lead to very confusing code. When using format(), it is always best to directly use it where the formatting is being applied.
@William Möller (https://teamtreehouse.com/williammller), thank you for participating in the Community. :thumbsup: If you could, however, in the future, provide an explanation with your answer. "Copy / Paste" answers with no explanations as to "why" don't provide a strong learning experience, so is not really an accepted practice in the Community.
Keep Coding! :) :dizzy:

it works fine on workspace 
name = "jacques"
subject = "Treehouse loves {}".format(name)

jacquesdiaquoi2 · Answer

name = "jacques"
subject = "Treehouse loves {} ".format(name)
I test my code using the print function on the python shell, 
it works fine, but according to workspace it's not the correct answer
