如果要彻底地产生一个和原对象完全独立的复制品,得使用深拷贝(deep copy): from copy import deepcopy m = [1, 2, [3, 4], [5, [6, 7]]] print('m:', id(m)) print([id(i) for i in m]) n = deepcopy(m) print('n:', id(n)) print([id(i) for i in n]) print(n is m...
最后一步是导入我们需要的Union、Structure和Array类。这些类位于_ctypes模块的命名空间中,我们可以使用“from … import …”语法来导入它们。 from_ctypesimportUnion,Structure,Array 1. 现在,我们可以使用这些类来扩展我们的Python代码的功能了。 结论 本文通过一个具体的例子,教会了你如何解决“ModuleNotFoundError”...

有关Python的import...和from...import...的区别 1、语法分析:首先fromAimporta1是从A模块导入a1工具(可以是某个 函数,全局变量,类),importA是导入整个A模块的全部内容(包括全部的函数,全局变量,类)。 2、内存分析:from...import...会在内存中创建并加载该模块工具的副本,当有另外一个程序导入时,会在内存...
