以下是sys.getsizeof()和asizeof.asizeof()函数之间的关系图。 erDiagram Object ||--o|- Size Size { int size } Object { string name int memory_usage } Object--|{sys.getsizeof()}|- sys Object--|{asizeof.asizeof()}|- asizeof 通过以上步骤和代码示例,你应该能够了解如何在Python中查...

typedef struct _object { PyObject_HEAD } PyObject; 1. 2. 3. 4. 5. 6. 7. 8. 当对象被创建出来给一个变量后,引用计数变成了 1,此后每被引用一次,引用计数的值增加。在 Python 代码中我们可以通过sys.getrefcnt()方法获取一个对象的引用计数: ...
This function returns the C string starting at memory addressaddressas a bytes object. If size is specified, it is used as size, otherwise the string is assumed to be zero-terminated. —— fromhttps://docs.python.org/3/library/ctypes.html?highlight=string_at#ctypes.string_at...
deep_getsizeof()是向下层递归的函数,并且可以计算Python对象图的的内存实际使用量。 ```python from collections import Mapping, Container from sys import getsizeof def deep_getsizeof(o, ids): “"”Find the memory footprin...
### Check object 'ob' size >>> sys.getsizeof(ob) / (1024 * 1024) 3072.0001373291016 ### Check current memory usage of whole process (include ob and installed packages, ...) >>> psutil.Process().memory_info().rss / (1024 * 1024) 323...
self.z=z>>>ob=Point(1,2,3)>>>print(sys.getsizeof(ob))64 内存减少的就相当明显了。 因此在使用大量object时,内存占用量如下: 这里的内存占用量减少主要是因为类实例内部存储的属性数量减少了。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ...
