If called with a tuple of type Tuple[int, ...]—which is-consistent-with Sequence[int]—then the type parameter is int, so the return type is List[int]; If called with a str—which is-consistent-with Sequence[str]—then the type parameter is str, so the return type is List[str]....

Changing hash values affects the iteration order of dicts, sets and other mappings. Python has never made guarantees about this ordering (and it typically varies between 32-bit and 64-bit builds). 另见PYTHONHASHSEED. 在3.3 版更改: 默认启用哈希随机化。 object.__bool__(self) 调用此方法以实现...

A pure-python version of the partial() function is now in the stdlib; in CPython it is overridden by the C accelerated version, but it is available for other implementations to use. (Contributed by Brian Thorne in bpo-12428.) gc New function get_stats() returns a list of three per-...
