change form tag in html as:
<form method="GET" action="output">
change urlpatterns in urls.py as:
path('output', views.output ,name ='output'),
add the following in your views.py:
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.

First have a look at Django forms 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.
Secondly have a look at https://flask-restful.readthedocs.io/en/latest/ with allows you to build a Webinterface.
Then you can use a Http POST request to send your data from Django to Flask, see https://stackoverflow.com/a/11324941/876847
This should loosely couple your apps so that they can run seperately

I have found a solution for the question, but I want to know whether there is any other way to pass data.
views.py
from django.shortcuts import render
import requests
# Create your views here.
def form(request):
return render(request,'hello/index.html')
def output(request):
name1=request.GET["name"]
if not name1:
name1=0
response = requests.get('http://127.0.0.1:5000/'+str(name1)).json()
#name = response.text
return render(request, 'hello/index.html', {'out': response['out']})
html file
<!DOCTYPE html>
<html>
<body>
<form action="output" method="GET">
Enter name: <br/>
<input type="text" name="name"> <br/>
<input type="submit" ><br/>
</form>
<div>
{{out}}
</div>
</body>
</html>
flask file
from flask import Flask,jsonify
app = Flask(__name__)
@app.route('/<name>',methods=['GET'])
def index(name):
return jsonify({'out' : "Hello"+ " "+str(name)})
if __name__ == '__main__':
app.run(debug=True)
