Google AppEngine告诉我我的int不是int

代码的相关部分：
pk = int(pk)
logging.info(\'pk: %r :: %s\', pk, type(pk))
instance = models.Model.get_by_id(int(pk))
pk: 757347 :: <type \'int\'>

从SDKclass IntegerProperty(Property): \"\"\"An integer property.\"\"\" def validate(self, value): \"\"\"Validate integer property. Returns: A valid value.
