It looks like Task 1 is no longer passing

hello, just stuck on this and not sure what i'm what i'm doing wrong. i know it's probably something minor and obvious...face palm btw, does the pink font mean anything?

"Alright, let's finish making our menu.

Combine the sundaes list into a new string, joining them with a comma and a space (", ").

Use that string with a .format() on our existing menu variable and replace the current value of menu."

When Task 1 no longer passes, check your newly added code for syntax errors.

task 1 = available = "banana split;hot fudge;cherry;malted;black and white"

task 2 = sundaes = available.split(";")

task 3 = menu = "Our available flavors are: {}.".format(sundaes.join(", "))

Hi Patrick, assuming you're on Task 2 when this occurs, make sure you don't include the period at the end of the string, because that period is intended to end the sentence, not to be included in the value for the menu variable.

menu = "Our available flavors are: {}."

If you're on Task 3, remember that the join method is "text to join between items".join(list_of_items_to_join) which is the reverse of the string.split("text") method.

Hope that helps!

Hi Evan.

I'm up to task three. i've passed through the first two. i'm sorry, i still don't really understand. here is an overview of what my code looks like at the moment. i decided to type it out since i don't how to copy/paste the code itself:

task 1 = available = "banana split;hot fudge;cherry;malted;black and white"

task 2 = sundaes = available.split(";")

task 3 = menu = "Our available flavors are: {}.".format(sundaes.join(", "))

so yeh, that's what my code currently looks like, i keep getting an error on task three.

You're so close on this one! You just need to reverse the order on the join method.

menu = "Our available flavors are: {}.".format(", ".join(sundaes))

hey patrick

so in the lesson edit kenneth was saying you have to first make the string then pass in what you're going to join the new string with in the parameter in this case we're doing the comma so it would be 

menu = "Our available flavors are: {}.".format(", ".join(sundaes))

Edit: Don't forget that space with the comma!

hope this helps you, guy
