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

In splitting and joining challenge task 3, I do not understand this: Where to get .format(sundaes.join(", ")) ?

I tried to add it directly into original menu variable, but then the task 1 is no longer passing. Thank you.

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

Where to get this?
.format(sundaes.join(", "))

I finally did it with only one line. So I wrote: menu += ", ".join(sundaes)

and it works Good Luck

This challenge isn't an easy one and a lot of people struggle with it, also the message that flashes when you get an error is misleading with the syntax when using .join().

Here's my solution to the problem, you call .join() on the string you want to use to combine something, then you pass it the thing you want to be joining together.

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

new_str = ', '.join(sundaes)
menu = menu.format(new_str)
