一种方法是使用一个纯文本编辑器,不如记事本(Windows)或TextEdit(Mac)。打开一个新的文本文件,输入你的Python代码(像print 1 + 1)。然后保存它为asXXX.py(XXX可以是任何描述性的文件名称)。 使用Windows的话,通过双击这个文件来运行它。在Mac上,打开终端,输入python,然后拖动你保存的文件到终端窗口并按Enter。
大多数控制台和终端一次只能使用一条物理线路。 When one pastes code into Shell, it is not compiled and possibly executed until onehits Retum. One may edit pasted code first lf one pastes more that one statement intoShell, the result will be a SyntaxError when multiple statements are compiled as...
