How to run this command in wsgi.py file in django?

Use nano.

So the command would be:

nano wsgi.py

Make sure you call the command in the directory the wsgi.py file is in.

Once the file is open, add the line to the end of the file. Then save with Ctrl-o, hit Enter to save the filename, and exit out of nano with Ctrl-x.

You can also append the line to the end of the file:

echo "python manage.py runserver 127.0.0.1:8000" >> wsgi.py

Then from the command line run

python3 wsgi.py

or

python wsgi.py

…depending on your Python versions and settings.

If you want wsgi.py to execute the command python manage.py runserver 127.0.0.1:8000 as a shell command, you can use something like this:

import os
from subprocess import call
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "django_project.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
call('python manage.py runserver 127.0.0.1:8000')

But I wouldn’t recommend doing it this way, If you are using apache or nginx to serve the django site and if you need to access it locally, you can make your website listen on *:80.
