Instance Method Objects {#instancemethod-objects}

::: index pair: object; instancemethod :::

An instance method is a wrapper for a PyCFunction{.interpreted-text role="c:type"} and the new way to bind a PyCFunction{.interpreted-text role="c:type"} to a class object. It replaces the former call PyMethod_New(func, NULL, class).

This instance of PyTypeObject{.interpreted-text role="c:type"} represents the Python instance method type. It is not exposed to Python programs.

Return true if o is an instance method object (has type PyInstanceMethod_Type{.interpreted-text role="c:data"}). The parameter must not be NULL. This function always succeeds.

Return a new instance method object, with func being any callable object. func is the function that will be called when the instance method is called.

Return the function object associated with the instance method im.

Macro version of PyInstanceMethod_Function{.interpreted-text role="c:func"} which avoids error checking.

Method Objects

::: index pair: object; method :::

Methods are bound function objects. Methods are always bound to an instance of a user-defined class. Unbound methods (methods bound to a class object) are no longer available.

::: index single: MethodType (in module types) :::

This instance of PyTypeObject{.interpreted-text role="c:type"} represents the Python method type. This is exposed to Python programs as types.MethodType.

Return true if o is a method object (has type PyMethod_Type{.interpreted-text role="c:data"}). The parameter must not be NULL. This function always succeeds.

Return a new method object, with func being any callable object and self the instance the method should be bound. func is the function that will be called when the method is called. self must not be NULL.

Return the function object associated with the method meth.

Macro version of PyMethod_Function{.interpreted-text role="c:func"} which avoids error checking.

Return the instance associated with the method meth.

Macro version of PyMethod_Self{.interpreted-text role="c:func"} which avoids error checking.
