Question

Python

Task: to replace the standard input and output of IPython.
What I did: replaced sys.{stdin,stdout,stderr}with my file-like objects.

from IPython.Shell import IPShellEmbed
IPShellEmbed()()

It works, but the output is sent to the shell from which the program is launched. You don't know why? Versions: IPython 0.10.2
, python - jython 2.5.2
