迭代协议定义了迭代的标准格式:一个执行__iter__和__next__(或 Python 2.x 中的__iter__和next)的对象就是一个迭代器,可以进行迭代操作,如下所示: classMyIterator(object):def__init__(self, xs): self.xs = xsdef__iter__(self):returnselfdef__next__(self):ifself.xs:returnself.xs.pop(0...

一个简单的 module 包含一系列 static 函数,这些函数的作用是将 python 能够 handle 的 PyObject 转换成为 C/C++ 代码能够 handle 的类型,比如我们写了一堆算法,是基于 boost.numeric.ublas 的,因此我们已经实现的操作对象是 boost::numeric::matrix<double>,通过一个简单的策略,我们将两者的指针进行转换(一般 Py...

The underlying file descriptor for the file object is then obtained by calling opener with (file, flags). opener must return an open file descriptor (passing os.open as opener results in functionality similar to passing None). 说明: 1. 函数功能打开一个文件,返回一个文件读写对象,然后可以对...
