</div><div>Actually, my questions are </div><div><br></div><div> 1. How to turn on console window(live) from Windows System while debugging Embedded PythonNet app?</div>
<div> 2. How to capture python script execution output from C# code?</div><div><br></div><div>I've been talking to <a href="mailto:Brad@fie.us" target="_blank">Brad@fie.us</a> about my issue which I can't get the output result of any python command using PythonEngine.RunString() or PythonEngine.RunSimpleString(). </div>
<div>I've been tried to debug simple code with Python.Runtime project, but can't find how to turn on this console window, nor capture the python script execution output.</div><div><br></div><div>What I'm trying to do is that I don't want to modify any python script when running a python script from C# code, so I have below code:</div>

I want to capture this output by RunString()/RunSimpleString() method, but it doesn't return any result except 'null'. It seems it isn't for getting output. </div>
<div><br></div><div>Then, while talking to Brad, his screenshot from his Mac OS with Mono displays the execution result output on an window like below, so wonder if windows environment can have same console window.</div>
<div>Previously, Oleksii and Sharon mentioned in the thread <a href="http://mail.python.org/pipermail/pythondotnet/2011-March/001103.html" target="_blank">http://mail.python.org/pipermail/pythondotnet/2011-March/001103.html</a>, but don't know it's already implemented or not. However, I can't find how to have same environment from my window system like Brad's Mac has.</div>
<div><br></div><div>So would you help me how to capture the python script output or have console window for debugging when I'm using embedded PythonNet? </div><div><br></div><div>Thank you,</div>
