Hi Mohan Abdul!

In your first section of code I see that you're trying to use the format method. If you were to go about this, the {} needs to be inside the quotes to work. Unfortunately even if that were inside the quotation marks, we wouldn't get the answer we expect. Instead we should take the members of the group and join them together with a string inbetween. We can use the helpful join method to do so. See 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"],
]
