[IPython-User] detect if the script is under ipython
Mon Nov 28 00:22:48 CST 2011
There are two ways that work in 0.11 and after:
if the name `get_ipython` exists, you are in IPython:
in_ipython = False
in_ipython = True
get_ipython() will return the current IPython instance, if you have cause
to query/manipulate it.
More programmatically, you can check if an InteractiveShell exists:
from IPython.core.interactiveshell import InteractiveShell
in_ipython = InteractiveShell.initialized()
