I did not know that join could be used like this. This is great. Note to self: ''.join(i) --> will join all items in the list with the specified character/character sequence inside ''. In this case, it will be empty, so the list will be joined without any characters inserted.

Actualy, this is commonly used method of converting a list to string. For your note: you can use "join" not only with lists, rather with all iterable types.
