Here's a version that makes it slightly easier to comprehend:
Q: I know how to zip sequences together:
| >>> a = (1, 2, 3)
| >>> b = (4, 5, 6)
| >>> z = zip(a, b)
| >>> z
| [(1, 4), (2, 5), (3, 6)]
but how do I reverse the process?
A: Use zip()!
| >>> a2, b2 = zip(*z)
| >>> a2
| (1, 2, 3)
| >>> b2
| (4, 5, 6)
zip as its own inverse might be even easier to comprehend if we call zip
by its more traditional name, "transpose".
