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

Need help understanding the question.

I just do not understand what the question is looking for.

I split available.

I created menu by using string formatting and the sundaes list.

I can create the display_menu variable by rejoining sundaes with commas.

I tried reassigning the variable menu on a seperate line and inline. Still not passing.

What part of this questions am I not understanding?

Thanks

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

Figured it out. I was using join wrong. I wish the challenges would respond with proper Python error messages. It would make tracking this stuff down much easier.

I'd suggest you use an online ide like this so you'll clearly see error messages and can easily print() things.

the join method is called on the delimiter string, with the collection as argument, so you have it backwards there.

(', ').join(sundaes)

is how you use it. you only need to use join once, to create a string of flavors, then that string becomes the argument for the format method called to form the menu string.

Thanks, James! I got Javascript Array.join() confused with Python join().
