Python Introducing Lists Build an Application Multidimensional Musical Groups

I am struggling with the final question of introducing lists. Can someone give me a hint on how to approach it?

I tried to join the lists to a new one then iterate through that and print but it didn't work. I have rewatched the video but it didn't help much.

groups.py
musical_groups = [
    ["Ad Rock", "MCA", "Mike D."],
    ["John Lennon", "Paul McCartney", "Ringo Starr", "George Harrison"],
    ["Salt", "Peppa", "Spinderella"],
    ["Rivers Cuomo", "Patrick Wilson", "Brian Bell", "Scott Shriner"],
    ["Chuck D.", "Flavor Flav", "Professor Griff", "Khari Winn", "DJ Lord"],
    ["Axl Rose", "Slash", "Duff McKagan", "Steven Adler"],
    ["Run", "DMC", "Jam Master Jay"],
]
# Your code here
for musical_group in musical_groups:
    print

You are creating the for loop so it will be able to run through each name in the list and print them out with a ',' separating each name. You can create a for loop for multi-dimensional lists.

Thanks so much, I have solved it. Appreciate the help.

So what you want to do is create the for loop, and you want to print out

", ".join('the variable created for loop') 
  • In your case it would be musical_group. Does that help?

What am I creating the for loop for? My understanding is that I can't used a for loop for multi dimensional list made up of multiple lists. Is there any documentation for how for loops and .join specificaly works with multi dimensiaonl lists. The video only mentions multi dimesional lists in the context of integers not strings.
