对于py 文件,Python 虚拟机会先对py 文件进行编译产生PyCodeObject 对象,然后执行了co_code 字节码,即通过执行def、class 等语句创建PyFunctionObject、PyClassObject 等对象,最后得到一个从符号映射到对象的dict,自然也就是所创建的module 对象中维护的那个dict。 import 创建的module 都会被放到全局module 集合 sys.mo...

The actual parameters (arguments) to a function call are introduced in the local symbol table of the called function when it is called; thus, arguments are passed using call by value (where the value is always an object reference, not the value of the object). [1] When a function calls...
