Combining multiple strings
F strings work great for a few variables, but what if you want to combine a whole list of variables into a string. You can use the "".join() method for just that. You put what you want to join the list items with inside the "" and then pass the list into the join() method. For example, if you want to join all the items in a list named cookies with a comma and space it would look like ", ".join(cookies).
In this exercise, you'll use these skills to convert a list of the top ten boy names into a sentence stored in a string.
