sys.getsizeof(object[, default]) 返回任意对象的字节大小。所有的内置对象都能返回正确的结果,但对于第三方扩展不一定适用。Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to.对于未提供获取大小的方式的对象,返回default。如果...

Pympler可用于检测,监控和分析python对象的内存占用情况。主要包括3个模块:asizeof 可准确获得python对象的大小;muppy用于在线监测Python应用程序;Class Tracker提供对所选Python对象生命周期的分析。 对象内存占用 sys.getsizeof 只能获得默认对象(str,list,dict等)的大小,对于复杂对象不适用。而asizeof能准确检测对象大...
