I'm using ubuntu 18.04, my default python3 version is Python 3.6.6
Found 3 version of python (3.5.2, 3.6.6, 3.7.0) in my pc. I'm not sure how this happened.
/usr/bin/python3.5: Python 3.5.2
/usr/bin/python3.6: Python 3.6.6
/usr/bin/python3.7: Python 3.7.0
Is it safe to remove python 3.5 and python 3.6 using
sudo apt-get purge python3.x and keep python 3.7 as my default?
because many said if i remove python 3.6 i won't be able to login after restart?
