| | | | PEP 584: Adding + and - Operators to the Built-In Dict Class
This PEP suggests adding merge + and difference - operators to the built-in dict class. The merge operator will have the same relationship to the dict.update method as the list concatenation operator has to list.extend, with dict difference being defined analogously. I think this is a pretty cool feature suggestion. Related discussion here.

pydis: A Redis Clone in Python 3 to Disprove Some Falsehoods About Performance
An experiment to disprove some of the falsehoods about performance and optimisation regarding software and interpreted languages in particular. In short, this is a Redis clone, written in < 250 lines of idiomatic Python code, providing a subset of Redis’ functionality for which there are official benchmarks. Pydis is ~60% as fast as the compiled C version of Redis, as measured in number of operations per second.

Understanding Python Slices
“Slices are both common and convenient ways to extract portions of Python data structures — usually with builtin objects, but also on your own. Once you get used to slices, you’ll see lots of uses for them, and wonder how you got along without them.”
