2,756 PointsStuck on this Musical Groups Challenge part 2
These are the instructions: "Can you loop through each group and output the members joined together with a ", " comma space as a separator, please?" I was thinking it would involve an if len(musical_groups) =>4: then print them But I can't seem to get that working. But is that even the right code?
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 groups in musical_groups:
group_members = ", ".join(groups)
print(group_members)
if musical_groups.len

231,275 PointsHere's a few hints:
- your test will need to go before the print, to determine whether to print or not
- lists don't have a "len" property, but you can check length using the "len()" function
- you'll want to check on the length of each group, not the whole master list
