Interval library in Python The Python module implements an algebraically closed interval arithmetic for interval computations, solving interval systems of both linear and nonlinear equations, and visualizing so
This paper introduces an extension to the Simpful library, enhancing it with capabilities for interval-valued fuzzy sets (IVFSs) and generalized fuzzy inference. Addressing the need for comprehensive uncertainty modeling in various applications, this extension offers intuitive definitions and operations ...

第四:setcheckinterval 如果程序确定是单线程,那么修改checkinterval为一个更大的值,这里有介绍。 第五:使用__slots__ slots最主要的目的是用来节省内存,但是也能一定程度上提高性能。我们知道定义了__slots__的类,对某一个实例都会预留足够的空间,也就不会再自动创建__dict__。当然,使用__slots__也有许多注意...
The portion library provides data structure and operations for intervals in Python.Support intervals of any (comparable) objects. Closed or open, finite or (semi-)infinite intervals. Interval sets (union of atomic intervals) are supported. Automatic simplification of intervals. Support comparison, ...
Python3.2前,GIL的释放逻辑是当前线程遇见IO操作或者ticks计数达到100(ticks可以看作是python自身的一个计数器,专门做用于GIL,每次释放后归零,这个计数可以通过 sys.setcheckinterval 来调整),进行释放。因为计算密集型线程在释放GIL之后又会立即去申请GIL,并且通常在其它线程还没有调度完之前它就已经重新获取到了GIL,就...

(which provides confidence values per word) is almost irresistible, but of course you don’t need complex projects to make use of parsedatetime: even allowing a user to type in a friendly and natural description of a date or time interval might be much more convenient than the usual but ...
