Ubuntu中python版本问题：
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150
查看python默认版本
python -V
切换版本：
sudo update-alternatives --config python3
Ubuntu中python升级到3.6：
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo apt install spyder3
sudo rm /usr/bin/python
sudo ln -s /usr/local/bin/python3.6 /usr/bin/python
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2
sudo update-alternatives --config python3

升级到python3.6 后使用pip install遇到问题：
import apt File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module> import apt_pkg ModuleNotFoundError: No module named ‘apt_pkg‘ Original exception was: Traceback (most recent call last): File "/home/osk/.local/bin/pip3", line 7, in <module> from pip._internal import main ModuleNotFoundError: No module named ‘pip._internal‘
解决方案：
重新将ubuntu16.04默认的python3.5版本设置为优先级
ubuntu16.04下python2、python3环境选择与python升级
