Python 3: The Power is Yours!
This book is an amazing resource for making the most of Python 3. This book truly makes it apparent what you're missing out on in the land of Python 2 and shows what can be accomplished more concisely in Python 3.
For example, as early as chapter 1, you're introduced to advanced unpacking techniques introduced in Python 3:
head, *tail = elems
The equivalent in Python 2 is:
head, tail = elems, elems[1:]
The chapter on generators and iterations techniques alone is worth the price of this book. It shows you how to "Loop Like a Native", all the way through using partial function application combined with lambdas to lazily loop over the contents of a file, ending when there's nothing left to read. Elegant!
There's more gems here, but I'll leave them for you to discover. The authors did a wonderful job of putting this book together, and I highly recommend this to anyone interested in becoming an effective Pythonista!
