:dir 指定生成代码的路径 :results output
:export (到html文件) code 只导出代码，results 只是结果 ，both :session my 可切换到生成的my buffer 操作 :tangle (创建源码） 文件名，yes, no :noweb yes 对tangle和export作用 :tangle xxx.py 输出文件 :var x=2
:shebang 指定码块的解释器

noweb:可以使用任何设定了名字的代码块，每次都是重新执行一遍所有相关代码。 session:后台会启动一个相应的解释器控制台，所有名称相同的代码块都会被加 载到该控制台，一直运行，并可以交互。
