如何在iPython笔记本中设置默认启动命令？

Question

我想在我创建的每个新笔记本中的几乎每个新笔记本中都带上几个单元格。

例如，当我创建一个新的笔记本，应该把

%matplotlib inline 
import matplotlib.pyplot as plt 

在默认情况下，细胞但不执行它。 我怎么能设置这样的东西呢？

定义设置默认启动的命令，你需要添加的命令在templete ipy_user_conf.py文件在您〜/ .ipython目录。
此模块在IPython启动期间导入。所以，你可以很容易做到：进口模块，配置扩展，更改选项，定义神奇的命令，把变量和函数的命名空间的IPython等
这里是样品ipy_user_conf.py：

# Most of your config files and extensions will probably start 
# with this import 

import IPython.ipapi 
ip = IPython.ipapi.get() 

# You probably want to uncomment this if you did %upgrade -nolegacy 
# import ipy_defaults 

import os 

def main(): 

    #ip.dbg.debugmode = True 
    ip.dbg.debug_stack() 

    # uncomment if you want to get ipython -p sh behaviour 
    # without having to use command line switches 
    import ipy_profile_sh 
    import jobctrl 

    # Configure your favourite editor? 
    # Good idea e.g. for %edit os.path.isfile 

    #import ipy_editors 

    # Choose one of these: 

    #ipy_editors.scite() 
    #ipy_editors.scite('c:/opt/scite/scite.exe') 
    #ipy_editors.komodo() 
    #ipy_editors.idle() 
    # ... or many others, try 'ipy_editors??' after import to see them 

    # Or roll your own: 
    #ipy_editors.install_editor("c:/opt/jed +$line $file") 


    o = ip.options 
    # An example on how to set options 
    #o.autocall = 1 
    o.system_verbose = 0 

    #import_all("os sys") 
    #execf('~/_ipython/ns.py') 


    # -- prompt 
    # A different, more compact set of prompts from the default ones, that 
    # always show your current location in the filesystem: 

    #o.prompt_in1 = r'\C_LightBlue[\C_LightCyan\Y2\C_LightBlue]\C_Normal\n\C_Green|\#>' 
    #o.prompt_in2 = r'.\D: ' 
    #o.prompt_out = r'[\#] ' 

    # Try one of these color settings if you can't read the text easily 
    # autoexec is a list of IPython commands to execute on startup 
    #o.autoexec.append('%colors LightBG') 
    #o.autoexec.append('%colors NoColor') 
    o.autoexec.append('%colors Linux') 


# some config helper functions you can use 
def import_all(modules): 
    """ Usage: import_all("os sys") """ 
    for m in modules.split(): 
     ip.ex("from %s import *" % m) 

def execf(fname): 
    """ Execute a file in user namespace """ 
    ip.ex('execfile("%s")' % os.path.expanduser(fname)) 

main()
