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

Trying to format commas in my list. Am I doing it right?

Here's my code

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

I'm trying to replace (';') with (', ') but it's not working so far. I'm new to Python in general so I'm pretty lost.

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

Hi Matthew,

It looks like you're really close, but try this:

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

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

Hope this helps!

This helped! I didn't know you had to have the ", " (commas) without parenthesis. That was messing me up and formatting the variables together.

This was tricky, thanks so much for the help!
