在Python中，函数id()返回对象的内存地址。( https://docs.python.org/2/library/functions.html#id )\xe2\x80\xa8\xe2\x80\xa8 在 python 中，如果两个变量具有相同的值，那么它们是否具有相同的地址?\xe2\x80\xa8\xe2\x80\xa8

In [30]: a = \'asdf\'\n\nIn [31]: hex(id(a))\nOut[31]: \'0x1082caa08\'\n\nIn [32]: b = \'asdf\'\n\nIn [33]: hex(id(b))\nOut[33]: \'0x1082caa08\'\n\nIn [34]: c = 2\n\nIn [35]: hex(id(c))\nOut[35]: \'0x1067295c0\'\n\nIn [36]: d = 2\n\nIn [37]: hex(id(d))\nOut[37]: \'0x1067295c0\' \n

下面这段代码中，代码的self._for_write含义是什么？

def create(self, **kwargs):
    """
    Create a new object with the given kwargs, saving it to the database
    and returning the created object.
    """
    obj = self.model(**kwargs)
    self._for_write = True
    obj.save(force_insert=True, using=self.db)
    return obj
