while i am not sure what really is the problem, you can save your code and run it through the command line and using "more" to pause the screen so you can look at the output.

IDLE operates in two different modes: with and without Subprocess. I've never seen this working WITH Subprocess (Start->Python 2.x->IDLE (Python GUI)).
Python 2.4.4 (#71, Oct 18 2006, 08:34:43) [MSC v.1310 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

Personal firewall software may warn about the connection IDLE
makes to its subprocess using this computer's internal loopback
interface. This connection is not visible on any external
interface and no data is sent to or received from the Internet.

IDLE 1.1.4 ==== No Subprocess ====

If you are using this, try WITHOUT subprocess (Right Click the .py file and choose Edit with IDLE. Let us know what happens.

If you are running another Tk GUI you will almost always have troubles.

The best way around this (if you must Run Module (F5) from IDLE) is to create your own output window. stdout can be set to any subclass of Frame containing a write() funtion. write(self, textStr) simply calls self.text.insert(textStr), where self.text is a Tk Text object. Instead of resetting stdout you may redirect the output of print:
Expand|Select|Wrap|Line Numbers
  1. print >> myOutputWindow, "some text"
or
Expand|Select|Wrap|Line Numbers
  1. myOutputWindow.write("some text")

AFAIK this will happen in any Tk Text widget, so the suggestion to use a separate frame for text won't help.

I would recommend installing the Squeezer extension for IDLE, which solves such issues very elegantly.
