对此先前的问题提出的建议是使用sys.getsizeof(),并引用:
>>> import sys
>>> x = 2
>>> sys.getsizeof(x)
14
>>> sys.getsizeof(sys.getsizeof)
32
>>> sys.getsizeof('this')
38
>>> sys.getsizeof('this also')
48
您可以采用这种方法:
>>> import sys
>>> import decimal
>>>
>>> d = {
... "int": 0,
... "float": 0.0,
... "dict": dict(),
... "set": set(),
... "tuple": tuple(),
... "list": list(),
... "str": "a",
... "unicode": u"a",
... "decimal": decimal.Decimal(0),
... "object": object(),
... }
>>> for k, v in sorted(d.iteritems()):
... print k, sys.getsizeof(v)
...
