[原文](http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/)

步骤1

```
sudo add-apt-repository ppa:jonathonf/python-3.6
```

---

```
步骤2
```

```
sudo apt-get update

sudo apt-get install python3.6
```

---

```
步骤3
要python3使用新安装的python 3.6而不是默认的3.5版本，请运行以下2条命令
```

```
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
```

最后，`python3`通过命令在两个python版本之间切换：

```
sudo update-alternatives --config python3
```

**更新：**由于此[错误](https://bugs.launchpad.net/ubuntu/+source/python3.6/+bug/1631367)
，gnome-terminal不会在步骤3之后启动，一种解决方法正在运行以下命令来重新创建符号链接：

```
sudo rm / usr / bin / python3 

sudo ln -s python3.5 / usr / bin / python3
```
