2,337 PointsI do not understand the final step of this code challenge and I need a step by step breakdown of what to do.
I can get through the first two steps but the third continues to elude me.
please help.
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "Our available flavors are: {}."
sundaes.join(", ")

Courses Plus Student 6,497 PointsFor the last step we need 2 things. First we need to display the string the challenge wants about "Our flavors..." Second we want to display sundaes with the first part. Like this:
available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "Our available flavors are:{}.".format(", ".join(sundaes))

Treehouse TeacherHi there! Remember that we use the curly braces in a string as a placeholder. Then we use the .format method to insert the value of a variable inside those curly braces. In this case, it will be a long list of ice cream sundaes!
So inside our .format method we want to get the result of the joining of the sundaes list so that it's formatted with a comma and space between each item. So the last piece of code can be written all on one line.
menu = "Our available flavors are: {}.".format(', '.join(sundaes))
This will take our menu string and then place the result of the joining of the sundaes string with a comma and space in between them in the place where the curly braces are.
Hope this helps!
