Where to Go From Here¶?

The quick functional implementation demonstrated here doesn't include all the things that the OO approach currently has. Foremost, this version needs to include modulo arithmetic. In [37]: augment((7,11),(1,1)) # Should be (0,0), in musical logic. Out[37]: (8, 12) In [38]: # This result is meaningless.

What if we went deeper?

Once you realize this is a good idea, the next thing you realize is....

Why would you ever do this?

The generalized problem From a pool of items, there are three attributes to select for. Specifying any two of them should produce one and only one result. More specifically... Musical intervals. A musical interval has: a quality (Major, Minor, Perfect, Augment, or Diminished) a number (Unison (1), Second (2), Third (3) ...

So... what's the point?

This post looks like a tutorial on list comprehension. Or maybe set operations. But really this post is about problem solving while writing code. The code solution to this problem is really easy... but only if you've figured out the problem you need to solve. I started with the following problem: Find the intersection of all non-empty sets, from an arbitrary pool of sets, not knowing which ones would be empty.
