Python Python Basics (2015) Python Data Types Use .split() and .join()

Need answer for python basics challenge task

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.

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

join function takes the list as an argument and add all the elements into a string, where each element is separated by the string upon which it is called.

e.g. list = ["a", "b", "c"] string = " and " string.join(list) = ' and b and c'

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)
