Python Introducing Lists Build an Application Multidimensional Musical Groups

Unable to finish Challenge Task 2

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

The below is for challenge 2: for group in musical_groups: if len(group) == 3: print(", ".join(group))

I'm not sure why this isn't passing the second challenge, as I feel like the code is specifically stating to print based upon the restriction of the lists' length equally to 3.

What am I missing?

Hey Auceanne Richer, your code actually works fine! The issue may be that you’re leaving both solutions in place instead of modifying Task 1 code to solve task 2. If submitted individually, the code passes the challenge.

Post back if you need more help. Good luck!!!
