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...

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.
