What I am missing in this simple code to print musical groups with 3 members?

Seems pretty straight forward but my error is that the first group isn't in the final results... 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 members in musical_groups:

members = ", ".join(members)
    if len(members) == 3:
        print(members)

'''

sorry for crappy format couldn't figure it out in this text block. 😅

If you join "members" before testing it, it gets converted into a string. Then, the len() of it will be the number of characters in the string and not the number of members in the group.
