I keep getting "Oops! It looks like Task 1 is no longer passing." when I complete the Task 3

This keeps happening

name.py 
name = ('Scott')
treehouse = ('Tree' + 'house')
email_greeting = (treehouse " loves " name)

You are missing "+" in your third line. Correct it or take that line out and run the task again. You might be able to get through.

name = ('Scott')
treehouse = ('Tree' + 'house')
email_greeting = (treehouse + " loves " + name)

Well, I thought parenthesis made your variables tuples, but as Chase pointed out, this is only true if there are commas, so Keerthi's answer should work, as does this

name = 'Scott'

treehouse = 'Tree' + 'house'

email_greeting = treehouse + ' loves ' + name

So, is it standard convention to leave out parenthesis when creating string variables, or is this a common choice?

Here is a link that addresses the issue of string in parenthesis versus a single element tuple with a string value:

Tupels will not form without commas separating the values

Frederick,

I am not sure what convention is exactly in regards to your question. You don't need parenthesis to set a string value to a variable, but technically it will work if you want to do it that way. Essentially adding parenthesis in a statement is affecting the orders of operation.

You do have to use parenthesis when you are passing a string to a function/method like print(), join(), split(), etc.

For now I would say do what makes the code easiest for you to read, but remain consistent.

In an upcoming section Kenneth Love will discuss PEP8 which evaluates convention and that would be a good time to investigate it.
