在linuxpython
Linux默認是已經安裝好了Python程序
目前來說，大多數的Linux發行版是安裝了兩個版本的Python程序
一個是Python 2.x
一個是Python 3.x
一些系統自帶的程序文件需要Python 2的支持，另外Python 3又是大勢所趨
所以，我們最好不要動系統的Python版本
需要使用哪個版本直接聲明就可以了
運行Python的方法：
我們在Linux系統上打開終端
輸入python
會彈出Python 2的版本和解釋器
輸入python3
會彈出Python 3的版本和解釋器
所以我們一般情況下，運行python 2的程序就輸入命令
python 程序文件
運行python 3的程序輸入命令
python3 程序文件
這里我們默認使用版本為Python 3
在終端輸入命令
Python3
彈出Python的解釋器以>>>開頭
我們可以在上面輸入Python程序
它會直接輸出結果
比如：
我們這里輸入32+46，輸出結果為78
輸入print('hello python')，輸出結果hello python
注意：當我們運行.py文件時，文件里的32+46是不會直接列印出來的
必須加列印命令
print(32+46)
我們退出python3解釋器的快捷鍵不是Ctrl+C
而是Ctrl+Z
