Question

我正在尝试为生产服务器上的Django应用程序运行Selenium测试。

我在 finally：子句中遇到语法错误。

我没有看到错误在哪里，所有测试都在开发中运行良好。

以下是代码：

 def activate_revision(self, user, revision):  
    self.title = revision.title  
    self.tagnames = revision.tagnames  

    self.body = self.rendered(revision.body)  

    self.active_revision = revision  

    # Try getting the previous revision  
    try:  
        prev_revision = NodeRevision.objects.get(node=self, revision=revision.revision-1)  

        update_activity = True  

        # Do not update the activity if only the tags are changed  
        if prev_revision.title == revision.title and prev_revision.body == revision.body \  
        and prev_revision.tagnames != revision.tagnames and not settings.UPDATE_LATEST_ACTIVITY_ON_TAG_EDIT:  
            update_activity = False  
    except NodeRevision.DoesNotExist:  
        update_activity = True  
    finally:  
        if update_activity:  
            self.update_last_activity(user)  
    self.save()

这是追溯：

Answer 1

回溯的第一部分表明它是生产中的Python 2.4。根据我上面的评论，问题是try..except..finally仅适用于Python 2.5及更高版本。升级生产或重写代码以将try..except嵌套在外部try..finally内。

** finally：*子句的语法错误在哪里？
