python - 这样的进口合法还是不推荐？

Question

像这样进行导入是否合法:

from webapp2_extras.appengine.auth.models import User as webapp2.User

我想将该对象称为 webapp2.User，尽管从技术上讲它不是。这是因为还有其他名为 User 的对象，所以我可能会将具有此模型的 Users 命名为 webapp2_user 之类的名称，以区别于 fbuser(通过“使用 facebook 登录”来的 facebook 用户)和 google 用户。这似乎是一个很好的类(class)，因为它允许将您的 google 或 facebook 其他帐户与此模型连接起来:

class User(object):

    def get_id(self):
        """Returns this user's unique ID, which can be an integer or string."""

    @classmethod
    def get_by_auth_token(cls, user_id, token):
        """Returns a user object based on a user ID and token.

        :param user_id:
            The user_id of the requesting user.
        :param token:
            The token string to be verified.
        :returns:
            A tuple ``(User, timestamp)``, with a user object and
            the token timestamp, or ``(None, None)`` if both were not found.
        """

    @classmethod
    def get_by_auth_password(cls, auth_id, password):
        """Returns a user object, validating password.

        :param auth_id:
            Authentication id.
        :param password:
            Password to be checked.
        :returns:
            A user object, if found and password matches.
        :raises:
            ``auth.InvalidAuthIdError`` or ``auth.InvalidPasswordError``.
        """

    @classmethod
    def create_auth_token(cls, user_id):
        """Creates a new authorization token for a given user ID.

        :param user_id:
            User unique ID.
        :returns:
            A string with the authorization token.
        """

    @classmethod
    def delete_auth_token(cls, user_id, token):
        """Deletes a given authorization token.

        :param user_id:
            User unique ID.
        :param token:
            A string with the authorization token.
        """

from webapp2_extras.appengine.auth.models import User as webapp2.User

是无效语法，Python 不允许您在 as webapp2.User 中使用 .，您应该使用 as webapp2_User 代替。
