[IPython-user] Using __IP.push()

[Frédéric Mantegazza]

I'm trying to use the __IP.push() method to have a line executed by IPython,
but it does not work. I think I don't use it in the correct way, but I can't
find the solution. Here is the error I get:

>>> __IP.push("print 4+4")
ERROR: Internal Python error in the inspect module.
Below is the traceback from this internal error.

Traceback (most recent call last):
