The pop function in Python operates by returning an element after removing it from a list. The index position of the element you want to remove can be specified when calling the procedure. If the index is left blank when using the pop() function, the final element is eliminated. The eleme...

显然它是 Python 代码在运行时动态产生的,更准确的说,是虚拟机在执行一个 def 语句的时候创建的。 当虚拟机在当前栈帧中执行字节码时发现了 def 语句,那么就代表发现了新的 PyCodeObject 对象,因为它们是可以层层嵌套的。所以虚拟机会根据这个 PyCodeObject 对象创建对应的 PyFunctionObject 对象,然后将函数名和 Py...
