I think there is something wrong with my pc. It shows that both python 3.5.2 and 2.7.12 are default. How to fix this?
And I tried to update the version of Ubuntu from 16.04 to 18.04 and I appeared an msg saying that it is not possible to update my python 3 is corrupted, I imagine it is because of this problem I described?
Anybody know what I should do? Thank you

Try setting the default Python as the 3.5 using the command:
sudo ln -sf /usr/bin/python3.5 /usr/bin/python3
If this doesn’t work, you can reinstall the packages from python3 using the command:
sudo apt-get install --reinstall python3
If it still doesn’t work, remove all packages python of update-alternatives and set Python 2.7 as standard using the commands:
sudo update-alternatives --remove-all python
sudo ln -sf /usr/bin/python2.7 /usr/bin/python
