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

Task 3

Alright, let's finish making our menu. Combine the sundaes list into a new string, joining them with a comma and a space (", "). Use that string with a .format() on our existing menu variable and replace the current value of menu.

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

Let's go step by step:

1. Combine the sundaes list into a new string, joining them with a comma and a space (", ").

To combine sundaes into a new new string, use the join method on the separator string "," with the sundaes list as the argument:

", ".join(sundaes)

2. Use that string with a .format() on our existing menu variable and replace the current value of menu.

Using the .format() method on the menu string, with the joined string from above as the argument:

menu = "Our available flavors are: {}.".format(", ".join(sundaes))

Thank you @Chris Freeman
