ModuleNotFoundError: No module named 'django', with virtual environment Python3.8

Trying to run Django App along with Apache2 in Python3.8 Virtual environment. When I enter in to the python shell, I could import django. But when accessing webpage, it says "django not found"

As per the /var/log/apache2/error.log, following is the error

[Sun May 03 02:56:14.209910 2020] [wsgi:error] [pid 21516] [remote 192.168.1.5:58968] from django.core.wsgi import get_wsgi_application [Sun May 03 02:56:14.209966 2020] [wsgi:error] [pid 21516] [remote 192.168.1.5:58968] ModuleNotFoundError: No module named 'django'

wsgi.py:

import os,sys

sys.path.append('/var/www/html/django-venv-py3.8/lib/python3.8/site-packages')

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'filebucket.settings')

application = get_wsgi_application()
