Memory management of imported modules in Python
问题
- Python的模块内存将分配在哪里？
- 内存分配是否会从内存中删除，以及何时删除？
英文:
I have some doubts with Memory management of imported modules in Python.
1 .where memory will be allocated for python's modules
2. is memory allocation deleted from the memory and when it is deleted.
答案1
得分: 1
-
在Python中，模块的内存是在程序执行期间分配的。当您将一个模块导入到您的程序中时，Python解释器会解析模块的代码，并为其中定义的所有对象、函数、变量和其他元素分配内存。
-
Python中对象的内存分配是由自动垃圾回收机制（垃圾收集器）管理的，它在对象不再使用时释放它们占用的内存。
它们何时不再使用？ - 当没有变量引用它们时。
重要的是，您可以通过诸如*'del'和'gc.collect()'等方法，而无需垃圾回收器的帮助来删除项目，以加速处理大量数据的程序。但通常情况下，垃圾回收器的工作足够了。在像C和C++*这样的语言中，没有这样的垃圾回收器，因此您必须手动管理所有内容。
英文:
1. In python, memory for a module is allocated during program execution. When you import a module into your program, the Python interpreter parses the module's code and allocates memory for all objects, functions, variables, and other elements defined in it.
2. Memory allocation for objects in Python is managed by an automatic garbage collection mechanism (garbage collector), which frees the memory occupied by objects when they are no longer in use.
When are they no longer used? - When there are no variables that refer to them
