I want to upgrade my python in fedora 20 to version 3.5 but after I installed the python.3.5.0.tgz file nothing changed and when I try to use python it still says that it's running the built-in version 2.7.5 How can I change that to the version I want I want to use Django and the version I want is only works on python 3.5
Fedora 20 is end of life, you should upgrade to a supported version of Fedora.
Now for the real answer:
Even Rawhide doesn't have python 3.5 installed.

You will have to install it yourself in a non-standard directory.
As of Nov 16, 2015, you can either upgrade to Fedora 23 and use a COPR repo, as described in this blog post on How to get Python 3.5 for Fedora 23 or use rawhide which has 3.5 now.

/usr/bin/python is still python2 and should stay that way. You should run /usr/bin/python3 to invoke... whatever version of py3 you've ended up with.
Fedora 23 which should be released end of October, will have Python 3 enabled by default.
