Printing nested lists of a list on different lines

Question

I have the following list:

l = [[1,2,3],[4,5],[6]]

I can get the following result:

[1, 2, 3]
[4, 5]
[6]

by using this code:

for n in l:
    print n

How can I get the following results which are not list:

1, 2, 3
4, 5
6

I am trying this:

for n in l:
    for s in n:
        print s

but it gives this:

1
2
3
4
5
6
