I'm unable to pull specific data from the list.
I've reviewed the videos in this section and I cannot find anything on pulling specific data from the list. It shows us how to access the list. I'm not seeing how to pull the trios from a list also in another challenge it wants me to pull all the continents stating with the letter A. There is not a video on how to access specific data type. Where can I find a video on this?
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 members in musical_groups: print(", ".join(members)) trios members == 3 print(trios)

Let's think this through.
We're looping through a list of lists. Each time through the loop,
members is the list.
We're being asked to only print the list of members if they are a trio. That means we need to add a condition before we print. What's the condition? If the number of items in the list is 3.
So in pseudo-code:
for each musical group in musical_groups: if the number of members in the group is 3: print the group's names
Make sense? How can you turn that into real Python code? You'll need to use a function that counts the length of the list.
Let us know how you make out.
