split, join

Here's my attempt but it's not working. I saw the post from Luis Wanus (I hope I his name right). I tried a few variations for what he had but none of them worked for me.

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

Here are the instructions given.

Alright, let's finish making our menu. Combine the sundaes list into a new variable named display_menu, where each item in the list is rejoined together by a comma and a space (", ").

Then reassign the menu variable to use the existing variable and .format() to replace the placeholder with the new string in display_menu.

If you're really brave, you can even accomplish this all on the same line where menu is currently being set.

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes=available.split(';')
menu="Our available flavors are: {} "
display_menu=menu #what are you trying to do here, this is not what is been asked

menu="Our available flavors are: {} ".format(display_menu)(", ".join(sundaes))
#you are trying to format, something, which is of not requested
#you have progressed well, I'd say comment out display_menu = menu
#then do not use, display_menu, when formatting, instead, format what is been asked (", ".join(sundaes))

#let me know, how you go with it.

Well, on the instructions, it says to combine the sundaes list into a new variable named display_menu where each item is rejoined together by a comma and a space (", "). So, what I included is just one of my attempts to get the last step in this challenge to work. I had previously tried: (", ").join(sundaes), then, (", ".joint(sundaes)), then, display_menu=menu.format(display_menu)(", ".join(sundaes)) I had also tried: menu="Our available flavors are: {} ".format(display_menu)(", ").join(sundaes) I tried many other variations but I tried to follow the directions as best I could but I am still struggling to understand what is meant by some of the instructions. So, because of this, I'm sure that I'm not getting things right, quite yet.

from what you say, I can understand, you have tried it with the right way, so we try bring it together for the 3rd step

#question - Alright, let's finish making our menu. Combine the sundaes list into a new variable named display_menu, where each item in the list is rejoined together by a comma and a space (", ").

# what you have done in your exercise is
#display_menu=menu --this step is wrong
#however you have mentioned, that you have tried

(", ").join(sundaes) # -- this step would be correct, if you are storing into the display_menu variable
(", ".joint(sundaes)),  # -- even, this would have been correct, if you are to store into display_menu, if not for the spelling "joint"
display_menu=menu.format(display_menu)(", ".join(sundaes))  #this line is not correct, one is you are storing into
# display_menu, the final outcome, and the other is formatting
menu="Our available flavors are: {} ".format(display_menu)(", ").join(sundaes) #this is wrong, why you have both
#display menu and the continuation

Ok, so they are all wrong. I don't know that I understand what you mean that a certain step would be correct if I was storing into the display_menu. Does that mean that, if I was going to put the menu items into a new variable named display_menu? That is what it seems like the instructions are telling me to do. Of course, since none of what I've tried has been correct that means, to me that I don't truly understand what the instructions are telling me to do. I will keep trying though because I want to understand. The joint, was a typo.

 #ok let us bring it together, am doing the break down way.

available = "banana split;hot fudge;cherry;malted;black and white"

#your code
sundaes=available.split(';') 
menu="Our available flavors are: {} "
display_menu=menu #as I mentioned this is wrong
menu="Our available flavors are: {} ".format(display_menu)(", ".join(sundaes))

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

#or else you could even do this way, bypassing not having anything in display_menu
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes=available.split(';')
menu="Our available flavors are: {} ".format(", ".join(sundaes))

Antonio, I thank you for your help on this. I'm going to have to come back to it though. I have some pressing home work assignments due for my programming and logic class. I am going to pick this back up, as soon as I can though. So, that I can continue with my learning on treehouse. I think I am learning more through treehouse than through the college courses that I'm taking but I can't pay for degree through treehouse.
