How to run an IPython magic from a script (or timing a Python script)

by

It depends a bit on which version of IPython you have. If you have 1.x:

from IPython import get_ipython
ipython = get_ipython()

If you have an older version:

import IPython.core.ipapi  
ipython = IPython.core.ipapi.get()

or

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

Once that’s done, run a magic command like this:

ipython.magic("timeit abs(-42)")

Note that the script must be run via ipython.
