This isn't Python loop syntax, are you also studying another language? Put on your "Python hat" and try again!

But also remember the instructions "Can you loop through each group and output the members joined together with a ", " (comma space) as a separator..." β€” the word "join‍ed" is a clue there to the name of a method you might use. :wink:

but im kinda confused though, plz giv me a hint then

A loop in python would generally skip using an index number and iterate through the items of a list like this:

for group in musical_groups:

Where "group" would represent the current item instead of "musical_groups[i]".

thnx Steven i managed to work it out
