Python: .join() and .split()

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.

can't figure this task out!! May I get some help!

you've split on the semicolon, so now you have a list of flavors. to use the join method, call it on the delimiting string, in this case ", " that you want to go between your elements (flavors) when forming the new string, and the argument to join is the list of elements to join, here the flavors. so ", ".join(list of flavors). that goes in display menu. then call the format method on the template string with display menu as the argument. template{}.format(display menu).
