Python Introducing Lists Build an Application Multidimensional Musical Groups

what does the output look like

What is the output supposed to look like? :/

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 group in musical_groups:
    s = ""
    for ppl in group:
        s = s + ppl +" ,"
    s = s[:-2]

I ran the solution through a workspace and here is the result:

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  

def fun(l): ... s = "" ... for mem in l: ... s += mem + ", " ... print(s[:-1]) ...

for group in musical_groups: ... fun(group)

I get the same output but it is saying fail?
