Here is a multi-dimensional list of musical groups. The first dimension is Can you

can any one help please

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_groups in group:
    print(", ".join(musical_groups (group)))

In the for loop, switch musical_groups with group, since group is the element is iterating through.

I think you are thinking way to complicated, but let's break it down a bit.

It seems like you have confused the list that you are iterating through with the name that you are assigning to the individual elements:

# Your code here
for musical_groups in group:

There is no list called 'groups', but you are trying to access it and assigning each element to 'musical_groups'

But there is a list named 'musical_groups' and you should try to pull the items out of that one:

for group in musical_groups:

This means you are able to write the .join function in a shorter way:

print(", ".join(group)

Because you are only joining the elements of one list which is already a sub-list of musical_groups, so you don't need to pull it out of the main list again. You are already having it in named 'group' .

Hope this helps at least a bit.

Happy coding

Your print statement has a missing bracket at the end.
