问题描述
我只想检查一下 PyObject 是否为 None 。我天真地期望从函数返回的任何无 Pyobject * 将是一个NULL指针,但是似乎
I would just like to check if a PyObject that I have is None. I naively expected that any None Pyobject * returned from a function would be a NULL pointer, but that doesn't seem to be the case.
所以:如何检查我的 PyObject * 是否指向无对象?
So: how do I check if a PyObject * of mine points to a None object?
我知道有像 PyInt_Check(PyObject *),但我找不到像 PyNone_Check 。我想我可以检查我的 PyObject 和 Py_None 之间的平等,但结果是我甚至不知道
I know that there are macros like PyInt_Check(PyObject *) around, but I couldn't find anything like PyNone_Check. I thought I could just check the equality between my PyObject and Py_None, but turns out I don't even know how to make equality comparisons with this library.
推荐答案
您可以直接与 Py_None 使用 == :
if (obj == Py_None)
