Python Introducing Lists Build an Application Multidimensional Musical Groups

I ran the code and it excludes musical_groups[0] in the output.

I answered with the following code but I don't understand why it doesn't work.

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

You're close, but you'll want to test the length of the current group (m) instead of the whole list:

    if len(m) == 3:

that makes sense. thank you so much.
