In Python, a class can inherit from another class, known as the base or parent class. The class inherited from the parent class is referred to as the derived or child class. By inheriting the attributes and methods of the parent class, the derived class gains the ability to extend and ...
The import statement includes the keyword import followed by the name of a module. The module name random is evaluated eagerly. The function call random.randint() is evaluated eagerly, and its value is returned immediately. All standard functions are evaluated eagerly. You’ll learn about genera...

1 使用python编写的代码(.py文件) 2 已被编译为共享库或DLL的C或C++扩展 3 包好一组模块的包 4 使用C编写并链接到python解释器的内置模块 为何要使用模块? 如果你退出python解释器然后重新进入,那么你之前定义的函数或者变量都将丢失,因此我们通常将程序写到文件中以便永久保存下来,需要时就通过python test.py方式...
