change form tag in html as:将 html 中的表单标签更改为：
<form method="GET" action="output">
change urlpatterns in urls.py as:将 urls.py 中的 urlpatterns 更改为：
path('output', views.output ,name ='output'),
add the following in your views.py:在您的 views.py 中添加以下内容：
def output(request):
data = request.GET['name']
return render(request, 'hello/**any template**.html',{'data' : data})
this will pass a variable data to your index.html Now you can use that in you any of templates with jinja.这会将变量数据传递给您的 index.html 现在您可以在任何带有 jinja 的模板中使用它。

First have a look at Django forms https://docs.djangoproject.com/en/3.1/topics/forms/#building-a-form .首先看看 Django 表单https://docs.djangoproject.com/en/3.1/topics/forms/#building-a-form 。 You'll then do not have to parse anything from you request, Django will to that for you.然后，您不必从您的请求中解析任何内容，Django 会为您解析。
Secondly have a look at https://flask-restful.readthedocs.io/en/latest/ with allows you to build a Webinterface.其次看看https://flask-restful.readthedocs.io/en/latest/允许你构建一个 Web 界面。
Then you can use a Http POST request to send your data from Django to Flask, see https://stackoverflow.com/a/11324941/876847然后您可以使用 Http POST 请求将数据从 Django 发送到 Flask，参见https://stackoverflow.com/a/11324941/876847
This should loosely couple your apps so that they can run seperately这应该松散地耦合您的应用程序，以便它们可以单独运行
