Joint: AttributeError

attendees = ["Ken", "Elena", "Steven"] attendees.append("Ashley") attendees.extend(["Tonny", "Jonny"]) optional_attendees = ["Mike", "Alex"] potential_attendees = attendees + optional_attendees print("There are", len(potential_attendees), "potential attendees currently.")

to_line = ", ".joint(attendees) cc_line = ", ".joint(optional_attendees) print("To: " + to_line) print("Cc: " + cc_line)

but it didn't work: AtrributeError: "str" object has no attribute in Joint Why is attendees here a string? I think did the same as Craig did....

I think you meant to use the string method named "join" (no "t") instead of "joint".
