How to completely uninstall python 2.7.13 on Ubuntu 16.04
提问by Lucas
I installed Python 2.7.13on Ubuntu 16.04according to this guide, and it became the default version as an alternative to the version 2.7.12. But, I wanted to completely remove Python 2.7.13and return back to the version 2.7.12as the default version since the pipcommand does not work with the following error.
我装Python 2.7.13上Ubuntu 16.04根据本指南，并成为默认的版本作为替代version 2.7.12。但是，我想完全删除Python 2.7.13并返回到version 2.7.12默认版本，因为该pip命令对以下错误不起作用。
bash: /usr/local/bin/pip: /usr/bin/python: bad interpreter: No such file or directory
Could you please help me how to completely remove Python 2.7.13from Ubuntu 16.04? Otherwise, could you please suggest how to fix the above error?

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.
注意：不建议从 Ubuntu 中删除默认的 Python，它可能会导致 GDM（提供图形登录功能的图形显示管理器）失败。
To completely uninstall Python2.x.x and everything depends on it. use this command:
要完全卸载 Python2.xx 一切都取决于它。使用这个命令：
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.
由于仍然有很多包依赖于 Python2.xx 所以你应该仔细查看 apt 想要删除的包，然后再让它继续。
Thanks, I hope it will be helpful for you.
谢谢，希望对你有帮助。

which python
Then remove all instances using:
然后使用以下方法删除所有实例：
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.
重复 sudo apt autoremove python（对于所有版本）应该这样做，然后安装 Anaconda 并管理 Pythons，如果你需要重新安装它，你喜欢。

我怎样做：
# Remove python2

# You already have Python3 but

sudo ln -s /usr/bin/python3 /usr/bin/python
# Same for pip
sudo apt install -y python3-pip
sudo ln -s /usr/bin/pip3 /usr/bin/pip
# Confirm the new version of Python: 3
