魔力函数
%lsmagic可以列出所有的魔力函数 magic 也可以使用 魔力函数后面直接跟问好的形式 例如 %page?
%quickref # 起始部分是一个对IPython各种用法的引用,其余部分是对%magic函数的迷你总结，包括全部帮助信息的首行
%psearch np.diag* 寻找函数
numpy.lookfor('convolution')

![command]
- !pwd
- %alias ls
- commands.getstatusoutput
!pwd
%run runpython文件 %who 查看定义变量 %who int 显示int的变量 %whos 显示变量值 %who_ls 返回列表 %who_ls int %reset 删除所有变量
%run my.py
%alias内嵌ls cd 等shell命令 %alias nss netstat -lptn
另一个可以简易执行shell命令的方法，是在命令前加一个感叹号（!）
通过$可以把python变量传递给shell命令
user = 'mouren'
process = 'bash'
!ps aux|grep $user |grep process
function
- %timeit
timeit x = 10 - %cpaste
- %debug allows you to enter post-mortem debugging. That is to say, if the code you try to execute, raises an exception, using %debug will enter the debugger at the point where the exception was thrown`
