Python basics? Bryce Linch

Not sure what 4th line is asking me to do? I understand I'm supposed to create a new variable and join in sundaes using ", " but the 4th line isn't making sense? Where does the {} go for the .format?

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

Hi Bryce,

You are very close, and the syntax of creating a string from a list is not very intuitive.

Lets go through this step by step.

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(';')

Right now sundaes is a list: ['banana split', 'hot fudge', 'cherry', 'malted', 'black and white']

To complete the 3rd challenge we need to turn that list into a string with each item separated by ', ', and assign it to a new variable. After we do that, we should put the new variable in the format().

The syntax of turning ['banana split', 'hot fudge', 'cherry', 'malted', 'black and white'] to 'banana split, hot fudge, cherry, malted, black and white' is:

', '.join(sundaes)

So the rest of the challenge should be:

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

Hope this helps, Idan

Hi Idan,

Thank you for very detailed and explanatory answer.

I think it is also worth mentioning that we have to put a line which create a new "flavors" string before the: menu = "Our available flavors are: {}.".format(flavors) otherwise the last will not be executed.

Thank you so much! Yeah the wording on this was very confusing, that's why I got tripped up! Thank you!
