The test wants me to use `.join(", ")` but everywhere else I am reading that it should be (", ").join(sundaes)?

Having trouble getting through the last part of this quiz.

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

The error message might be misleading.

It doesn't want you to use join with the arguments reversed, but it was guessing that you might have reversed them.

Your actual issues are:

  • you don't need to put parentheses around the string with the comma and space
  • you forgot that the challenge said "...reassign the menu variable..."

So after you remove the extra parentheses and assign the string you produce on the last line back to menu, you should pass.

Thank you! This got me around the point I was stuck on. Just passed with:

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

Exactly right. :+1: But remember to use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:
