This site kept showing "your code took too long to run" after I refreshed many times...

and I also checked my internet connection! But it still shows that. Somebody help me fix that?

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:
    to_line = ", ".join(musical_group)
    while len(musical_group) != 3:
        continue
    print(to_line)

Hey Megan, Task 1 of 2 is asking you to loop through each group and print the names of the groups. Here is how I did it. 

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

For task 2 of 2, it is asking you to only print IF the amount of members is 3. So you need to simply add an if statement that checks what the length of the nested lists. 

for group in musical_groups:
    if len(group) == 3:
        print(", ".join(group))
