Answer 1

If you have pip, you can also do a

pip freeze

and it will show your all component version including Django .

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

Answer 2

you can import django and then type print statement as given below to know the version of django i.e. installed on your system:

>>> import django
>>> print(django.get_version())
2.1

Answer 3

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

Answer 4

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The potential problem with simply checking the version, is that versions get upgraded and so the code can go out of date.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

Answer 5

The most pythonic way I've seen to get the version of any package:

>>> import pkg_resources;
>>> pkg_resources.get_distribution('django').version
'1.8.4'

This ties directly into setup.py: https://github.com/django/django/blob/master/setup.py#L37

Also there is distutils to compare the version:

>>> from distutils.version import LooseVersion, StrictVersion
>>> LooseVersion("2.3.1") < LooseVersion("10.1.2")
True
>>> StrictVersion("2.3.1") < StrictVersion("10.1.2")
True
>>> StrictVersion("2.3.1") > StrictVersion("10.1.2")
False

As for getting the python version, I agree with James Bradbury:

>>> import sys
>>> sys.version
'3.4.3 (default, Jul 13 2015, 12:18:23) \n[GCC 4.2.1 Compatible Apple LLVM 6.1.0 (clang-602.0.53)]'

Tying it all together:

>>> StrictVersion((sys.version.split(' ')[0])) > StrictVersion('2.6')
True

Answer 6

Type the following command in Python shell

import django
django.get_version()
