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

Don't know what i'm doing wrong

banana.py 
available = "banana split;hot fudge;cherry;malted;black and white"

sundaes = available.split(";")

menu = "Our available flavors are: {}."

Hi Steve, on the last task, you have forgotten to format in the joined version of sundaes. .join() can be used on a string to join a list together with each item seperated by that string:

available = "banana split;hot fudge;cherry;malted;black and white"

sundaes = available.split(";")

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

Thanks, Haider

What does .format do?

.format allows you to format something into the curly braces in a string. For example, if i had the following string:

message = 'Hello my name is {}'

you could put your name into the string by calling format on it.

print(message.format('Haider'))

This would give you the following message:

'Hello my name is Haider'
