As an exercise, you'll be given some strings in a list; each string in the list represents a single line from a hypothetical file, and there are different fields of data on each line separated by commas. Your task is to write a function that will return a list of tuples, in which each line has been properly broken up into a tuple. **NOTE: When you're using `str.split()` to break sequences on whitespace, there's an important difference between `str.split()` and `str.split(' ')`. When you don't specify a character to split on, Python will split strings based on *any length of whitespace*, but if you tell Python to split on just a single space, it will find zero-length strings in between two single spaces. For most applications, you *probably* want to split on any kind and any length of whitespace, right?**">
