ipython很好用，但是如果在ipython里已经import过的模块修改后需要重新reload就需要这样
In [1]: %load_ext autoreload In [2]: %autoreload 2 In [3]: from foo import some_function In [4]: some_function() Out[4]: 42 In [5]: # open foo.py in an editor and change some_function to return 43 In [6]: some_function() Out[6]: 43
如果想在ipython每次启时自动加载，步骤如下
it may be necessary to generate one first:
1、运行下面的command用来产生ipython_config.py文件
ipython profile create
2、gedit ~/.ipython/profile_default/ipython_config.py添加:
c.InteractiveShellApp.exec_lines = []
c.InteractiveShellApp.exec_lines.append('%load_ext autoreload')
c.InteractiveShellApp.exec_lines.append('%autoreload 2')
