can you help me for this code please

i can not complete it

groups.py
```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"],
]

list_number=1
for list in musical_groups:
print(list)
list_number+=1

abc= ", ".join(list)
```

You're overcomplicating stuff. Since `musical_groups` is a two-dimension object, get hold of each list in the second dimension by creating a `for loop` targeting the second dimension and printing each item of each list.

Taking your solution into account;

```list_number=1 ðŸ‘ˆ# Why?
for list in musical_groups:ðŸ‘ˆ#Here you're targeting the first dimension not the second. Since musical_groups is a list of
#lists specify the inner dimension of the musical_groups which is musical_groups[0] here 0
#is the first list within musical_groups.
print(list)
list_number+=1

abc= ", ".join(list)
```

So let me give you a template:

```for x in musical_groups[]: ðŸ‘ˆ#Since there are 7 lists within musical_groups' list, use index to target all of them.
print(", ".join(x))
```
