Python Django-runserver错误-值错误：源代码字符串不能包含空字节

我刚开始学习django，并在网上试用了一些教程。请帮忙。这只是一个小型web应用程序，它接受用户输入并将其显示在留言板上

我正在使用windows和django 1.11.7。我使用用于python的升华文本编辑器

我不知道这个错误是什么意思。如果有人能帮忙，那将大有裨益。这是我得到的错误：

这是消息\u app/url文件：

from django.conf.urls import url

from .views import Home_page_view

urlpatterns = [
    url(r'^$', Home_page_view.as_view()),
]

谢谢你

你能检查一下你的最后一个代码块吗：代码周围似乎有错误的反勾号，而且第一行不应该是代码的一部分（而是指示文件名）。鉴于回溯，带有空字节的文件可能是

message_app/urls.py

，而不是你显示的那个。@Evert Hi。我现在也包括了这个文件。如果有一个隐藏的空字节，它可能在StackOverflow上不可见。尝试在两个

url.py

文件上运行Python可执行文件，看看它们是否可以编译。嗨，你有解决问题的方法吗？我也有同样的问题。谢谢

from django.conf.urls import url

from .views import Home_page_view

urlpatterns = [
    url(r'^$', Home_page_view.as_view()),
]
