通过类名MyClass来调用static_method2方法。 流程图 StartDefine static_method1Define static_method2Call static_method2 from static_method1End 上面的流程图展示了静态方法内部调用其他静态方法的过程。首先定义了static_method1和static_method2两个静态方法,然后在static_method1中调用了static_method2,最终结束。

builtin_methods 中每一个函数对应一个 PyMethodDef 结构,会基于它创建一个 PyCFunctionObject 对象,这个对象是Python 对函数指针的包装。 代码语言:cpp 代码运行次数:0 运行 AI代码解释 structPyMethodDef{constchar*ml_name;/* The name of the built-in function/method */PyCFunction ml_meth;/* The C fun...
#define BUILD_TEST //使导出函数生效 #include "test.h" #include "stdio.h" #include "pch.h" int sum(int a, int b) { return a + b; } 注意,这里要点击64位,再点击生成(因为目前大部分电脑安装Python解释器是64位的,否则默认生成32位的动态库,会导致无法调用)这是一个很隐蔽的坑!!!

In this tutorial, you'll compare Python's instance methods, class methods, and static methods. You'll gain an understanding of when and how to use each method type to write clear and maintainable object-oriented code.
#define _MODULE_A_H int foo(int x, int y); #endif 在模块B中调用该函数: //模块B实现文件 moduleB.cpp #include"moduleA.h" foo(2,3); 实际上,在链接阶段,连接器会从模块A生成的目标文件moduleA.obj中找_foo_int_int这样的符号!!!,显然这是不可能找到的,因为foo()函数被编译成了_foo的符号...
