You can use one of the below methods to check which version of Django you installed:

  1. Using python bin:

    $ python -m django --version
    3.0.5
    
  2. Using pip freeze:

    $ pip freeze
    asgiref==3.2.7
    Django==3.0.5
    pytz==2020.1
    sqlparse==0.3.1
    

    This method gives you all python packages that you installed. To see only Django:

    $ pip freeze | grep Django
    Django==3.0.5
    
  3. Using pip show:

    $ pip show django

All done!
