是否安装了 Python：（Raspberry Pi Ubuntu）

Question

16.04 安装在 树莓派 3

尝试验证 python 版本未指示安装的 python 版本（如果有）：

ubuntu@ubuntu:~$ python -V
The program 'python' can be found in the following packages:
 * python-minimal
 * python3
Try: sudo apt install <selected package>

ubuntu@ubuntu:~$ python --version
The program 'python' can be found in the following packages:
 * python-minimal
 * python3
Try: sudo apt install <selected package>

Ubuntu 不是默认安装 python 吗？

该程序/usr/bin/python是 Python 2.x，默认情况下未安装。您需要使用python3。
