我遵循了YouTube上关于django的教程，但当我创建一个页面并尝试加载它时，我遇到了一个问题。服务器似乎运行正常，但当加载我创建的页面时，我收到了以下错误：
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/playground/hello
Using the URLconf defined in storefront.urls, Django tried these URL patterns, in this order:
admin/
The current path, playground/hello, didn’t match any of these.
You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
这是设置的代码.py文件

您的django项目中是否真的有playground文件夹和urls.py文件？从这里我只能看到你的应用程序名称是storefront和urls.py文件。因此，请确保包含现有的url配置。
来自文档：
每当Django遇到include((时，它就会截断与该点匹配的URL的任何部分，并将剩余的字符串发送到包含的URLconf中进行进一步处理。
我也遇到了同样的问题，如果你或任何人正在寻找这个问题的答案，很简单，你必须在执行之前保存更改，在VS代码中，我们往往会忘记这样做。一旦你这样做了，它就像一个符咒一样工作。一旦你让它工作起来，你很可能会丢失默认主页，这很正常，你不必担心。
im也关注youtube totarial，我遇到了同样的问题，原因是我保存了所有文件后没有保存所有文件(ctrl+s(，然后刷新了浏览器，它正常工作
