Question

我正在使用Python3 / flask。当我尝试访问网址时，它会显示“未找到名称或服务”。但是当我尝试使用我的本地编辑器Pycharm时，我能够访问该URL。我知道PythonAnywhere只允许列入白名单的URL，否则会出现403禁止错误。在我的情况下，我得到的服务没有找到＆＃39;错误因此不是PythonAnywhere限制访问的情况。我的代码如下（由于安全问题，无法共享凭据）

                line = 1

                try:
                    USERNAME = "******"
                    PASSWORD = "******"

我在第6行遇到异常。例外情况如下 - （我有一个前端。这里的图片是我前端的截图）
