try following to see all instances of python

whereis python
which python

Then remove all instances using:

sudo apt autoremove python

repeat sudo apt autoremove python(for all versions) that should do it, then install Anaconda and manage Pythons however you like if you need to reinstall it.

caution   It is not recommended to remove the default Python from Ubuntu  it may cause GDM Graphical Display Manager  that provide graphical login capabilities  failed   To completely uninstall Python2 x x and everything depends on it  use this command   sudo apt purge python2 x-minimal   As there are still a lot of packages that depend on Python2 x x  So you should have a close look at the packages that apt wants to remove before you let it proceed   Thanks  I hope it will be helpful for you
