Python basics, Use split and join. (Need help)

I cant figure out the last step of this assignment, i would love to see the solution, and possibly an explanation, if anyone has the time?

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

You are very close, but it seems like you're not using .format() correctly + you made a typo in your -join() (should be .join())

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(';')
display_menu = ', '.join(sundaes)  # Here you join the list 'sundaes' into a string
menu = 'Our available flavors are: {}.'.format(display_menu)  # Here you format the string using the 'display_menu'

You could also do the format() and join() in one step like this:

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

I hope this makes more sense? :-)

I would recommend watching the previous video(s) again, but join() is used like this (this confuses a lot of people):

" ".join(some_list_here)  # could also be ", ".join(some_list_here) if you want to join the items with comma :-)

Also, the variable you are using in .format() should be the string you get after joining the list.

I hope this is somewhat helpful :-)

this one confused me as well. I struggled with it for an hour or so. I would really recommend you try the "brave" method. It's a more concise way of writing it. but yes Henrik is right with the [", ".join(list)] instead of [list.join(", ")].

I'm primarily writing this to tell you to take heart, and don't think you're no good. I thought I was stupid after this question haha.

I still dont understand this assignment my new code look like this: available = "banana split;hot fudge;cherry;malted;black and white" sundaes = available.split(";") menu = "Our available flavors are: {}.".format(sundaes) display_menu = ", "-join("sundaes") But now it says: Oops it looks like task 1 is no longer passing.
