Added Python assignment - Daniel Chung

Created 4 functions:

1. Health data assignment using lists and csv.reader()
2. Health data assignment using dictionary and csv.DictReader()
3. Average of stream of input of numbers from class
4. FizzBuzz using a list comprehension
    - I'm not too sure how the 'else' command in the list comprehension works, any thoughts?
Wow, I would not have thought to do this... nice.
