The C structure of the objects used to describe built-in types.
This is the type object for type objects; it is the same object as type in the Python layer.
Return true if the object o is a type object, including instances of types derived from the standard type object. Return false in all other cases.
Return true if the object o is a type object, but not a subtype of the standard type object. Return false in all other cases.
Clear the internal lookup cache. Return the current version tag.
Return the tp_flags member of type. This function is primarily meant for use with Py_LIMITED_API; the individual flag bits are guaranteed to be stable across Python releases, but access to tp_flags itself is not part of the limited API.
New in version 3.2.
Invalidate the internal lookup cache for the type and all of its subtypes. This function must be called after any manual modification of the attributes or base classes of the type.
Return true if the type object o sets the feature feature. Type features are denoted by single bit flags.
Return true if the type object includes support for the cycle detector; this tests the type flag Py_TPFLAGS_HAVE_GC.
