Is .join correct on Menu indexed line?

checking Menu index line

banana.py 
available = "banana split;hot fudge;cherry;malted;black and white"
avaliable = "banana split;hot fudge;cherry;malted;black and white".split(';')
['banana split', 'hot fudge' , 'cherrymalted' , 'black and white']
sundaes = available.split(";")
menu = "Our avaliable flavors are: " +' ,'.join(avaliable)

Martin Rollins we need to use the join method on sundaes and store the result in a new variable named display_menu.

Once that is done you can pass display_menu in your format method.

That seems to be one of several issues:

  • lines 2 and 3 don't relate to the instructions and should be removed
  • "available" is misspelled as "avaliable" ("l" before "i") in two places
  • the join is connecting with ' ,' (space comma) instead of ', ' (comma space)
  • the menu string is missing the placeholder ("{}")
  • the final step should use .format() to fill the placholder (you won't need to concatenate anything)
