multi-dimensional list

Here is a multi-dimensional list of musical groups. The first dimension is group, the second is group members.

Can you loop through each group and output the members joined together with a ", " comma space as a separator, please?

please help

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"],
]

You need to do a for loop to iterate with each list:

for musical_group in musical_groups:

Then, join each group with the .join function:

groups = ", ".join(musical_group)

Now print them, to print them you had to assign a variable to the function(the variable is groups):

print(groups)
