 vs list()
Any reason in this lesson he uses  to create a list in line 1 but list() in line 2? I "think" they're the same but somewhat confusing. He should mention if this is so in the voiceover, or which method he prefers. Otherwise () is just a tuple.

Hi William - The parenthesis here cannot be those used for creating a tuple because they are followed by a method name, list(). To use list() you need to pass an iterable to it, as you can see in the video. So this code:
vowels = list('aeiou')
is equivalent to
vowels = ['a', 'e', 'i', 'o', 'u']
