que.pyx:6:38: Cannot convert Python object to 'Queue *' 检查拼写que.cqueue_new() que.pyx:11:21: Invalid types for 'is_not' (Python object, void *) 你不能使用is not对于C指针。采用!= que.pyx:12:14: undeclared name not builtin: cqueue 检查拼写。
deffoo():# 这种声明方式也是可以的, 和上面的方式是完全等价的cdef:intiintN =2000floata, b =2.1# 但是注意声明的变量要注意缩进# Python 对缩进是有讲究的, 它规定了 Python 中的作用域# 所以我们看到 Cython 在语法方面还是保留了 Python 的风格 关于静态和常量 如果你了解 C 的话,那么思考一下:如果想...

虽然整型在底层对应 PyLongObject,但是会转成 PyObject * 存在列表里面,因为 C 中的数组只能存放相同类型的元素(指针也是相同类型的指针),然后用的时候再转回对应的类型,而 PyObject 里面的 ob_type 成员便是指向对应类型对象的指针。所以 Python 中的列表可以存储任意类型的变量,因为它们都是一个 PyObject *。但...
basestring类型可以表示str类型和unicode类型,也就是说所有Python2和Python3的Python文本字符串类型。这可以被用来测定文本变量的类型,文本里面正常地含有unicode文本(至少Python3)但是在Python2种必须额外接受str类型,这是为了向下兼容。这和bytes类型是不兼容地。它应该在一般地Cython代码中很少的使用,因为一般的object类型...
Thedeclaration in the method signature falls into the same category. If the function was a Python function returning a Python object value, CPython would simply returninternally instead of a Python object to indicate an exception, which would immediately be propagated by the surrounding code. The ...
