Getting the Size of an Object in Python2015-11-22
Recently, I found myself wondering how much memory a Python list I had in my environment was using. So I searched and found the following very handy function for the curious minds or desperate debuggers.
sys.getsizeof(object[, default]) Return the size of an object in bytes. The object can be any type of object. All built-in objects will return correct results, but this does not have to hold true for third-party extensions as it is implementation specific. Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to. If given, default will be returned if the object does not provide means to retrieve the size. Otherwise a TypeError will be raised. getsizeof() calls the object's __sizeof__ method and adds an additional garbage collector overhead if the object is managed by the garbage collector.
