It is possible to override this behavior by specifying a _pack_ class attribute in the subclass definition. This must be set to a positive integer and specifies the maximum alignment for the fields. diary wrapper https://pixelmotionuk.com

WebSince Python 2.2, the PyTypeObject itself has become dynamic which allows C types that can be “sub-typed “from other C-types in C, and sub-classed in Python. The children types inherit the attributes and methods from their parent (s). There are two major new types: the ndarray ( PyArray_Type ) and the ufunc ( PyUFunc_Type ). citigroup pension scheme ukWebIn the Cython syntax, the words struct, union and enum are used only when defining a type, not when referring to it.
