Basically the same as bcoughlan's answer, but here it is as an executable command:

$ python -c "import django; print(django.get_version())"
2.0

If you have installed the application:

$ django-admin --version
3.2.6

Go to your Django project home directory and do:

./manage.py --version

>>> import django
>>> print(django.get_version())
1.6.1

I am using the IDLE (Python GUI).

If you have pip, you can also do a

pip freeze

You can pipe it through grep to get just the Django version. That is,

josh@villaroyale:~/code/djangosite$ pip freeze | grep Django
Django==1.4.3

As you say you have two versions of Python, I assume they are in different virtual environments (e.g. venv) or perhaps Conda environments.

When you installed Django, it was likely in only one environment. It is possible that you have two different versions of Django, one for each version of python.

In from a Unix/Mac terminal, you can check your Python version as follows:

$ python --version

If you want to know the source:

$ which python

And to check the version of Django:

$ python -m django --version

For Python:

import sys
sys.version

For Django (as mentioned by others here):

import django
django.get_version()

The potential problem with simply checking the version, is that versions get upgraded and so the code can go out of date. You want to make sure that '1.7' < '1.7.1' < '1.7.5' < '1.7.10'. A normal string comparison would fail in the last comparison:

>>> '1.7.5' < '1.7.10'
False

The solution is to use StrictVersion from distutils.

>>> from distutils.version import StrictVersion
>>> StrictVersion('1.7.5') < StrictVersion('1.7.10')
True

There are various ways to get the Django version. You can use any one of the following given below according to your requirements.

Note: If you are working in a virtual environment then please load your python environment

Terminal Commands

1. python -m django --version
2. django-admin --version or django-admin.py version
3. ./manage.py --version or python manage.py --version
4. pip freeze | grep Django
5. python -c "import django; print(django.get_version())"
6. python manage.py runserver --version
