...is returned to the generator's caller. It can be thought of as a generator-based version of the return keyword.
A generator allows you to suspend execution of a function and resume it later. A generator can be used to schedule your functions with a technique called trampolining.

Why would introducing useless MOV instructions speed up a tight loop in x86_64 assembly?
...ain, but can be avoided by using dependency breaking idioms. In processors based on Intel Core micro-architecture, a number of instructions can help clear execution dependency when software uses these instruction to clear register content to zero. Break dependencies on portions of registers between ...

This means users with pip 8.1+ running on a glibc-based distribution (almost everything except Alpine Linux) and on x86/x86-64 no longer need a compiler or headers because you'll get a precompiled wheel automatically.

What is time_t ultimately a typedef to?
...en read by other operating systems, it'd be silly to define the filesystem based on such implementation-dependent types. For example, the same filesystem might be used on both 32-bit and 64-bit systems, and time_t might change size. Thus, filesystems are need to be defined more exactly ("32-bit sign...
