Task 1 exactly the same... but still an error message

One quirk about the multi-task challenges is how they re-check all the previous tasks in order. This can get confusing if you have done something (such as introduced a syntax error) that invalidates the entire program. That causes all tasks (starting with the first) to fail.

In this case, the new third line has several syntax errors:

• it seems to have two separate assignments on the same line
• the "format" method (which is for strings) is being applied to a list
• there is a stray string following the "format" call

Looks like you just have some syntax errors.

First, Don't make an assignment in your template string, do that before

Second, you want to join the list of sundaes, not format them

Third, To use template strings in python, you don't need to quotes (") inside the curly braces ({}, also pre-pend your string with an f

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
display_menu = ", ".join(sundaes)
menu = f"Our available flavors are: {display_menu}."
