And what if the area code was, say, 4 digits long?

You can mix single and double quotes in a string. For example, instead of writing:

'Greg\'s House'

you can simply write:

"Greg's House"

and avoid using backslashes.

why didnt you use escape characters

You need to include the given variables, not literally to hard code them.

The whole point here is that it's not a list comprehension.

If it were a list comprehension, then the whole list would be built, and all would be called on it afterwards. But it's a generator comprehension, which produces elements lazily, one by one, as they are iterated over.

I would have never thought of this. I like it and will deffinately be using it moving forward :)

How does this satisfy all 5 lines of the test?

I Can only get the first line to pass, and never the second

Absolutely Painlich

länglich!!!

Not bad at all! :-)

Lääänglich!
