Django does not dominate Python jobs at all. Just look at this:

Python 19,381 jobs http://www.indeed.com/jobs?q=python&l=

Django 1,057 jobs http://www.indeed.com/jobs?q=Django&l=

Django doesn't even dominate Python web related jobs if you accept "Python JavaScript" as a proxy for Python web related jobs: http://www.indeed.com/jobs?q=Python+Javascript&l= gives you 4,671 jobs. Granted for many of them Python is not the main skill asked for.

Python is used by sysadmins and by scientists and even in financial services combined with C++. The combination of Python and C++ is requested 7,165 times. Compare that with "PHP C++" 3,051, "Ruby C++" 2,277, "Java C++" 25,675 and "C# C++" 13,045.

So Python has become a language that is very broadly used in all kinds of development jobs.
