The given outer list contains group members contained in a list, aka a list-of-lists.
- Can you loop through each group [in the outer list]...
This is the usual loop through a list:
for inner_list in outer_list:
- output the members joined together with a ", " comma space as a separator
A list can be joined together into a string using the str.join() method. This uses a string as the glue characters between a list of strings. So,
“, “.join(inner_list)
Creates a larger string with inner_list items comma-space separated.
Post back if you need more help. Good luck!!!
