Unable to launch Python in console

I am looking for a console application that will support Python. Your code looks great, but fails to work with Python.exe (v2.7.8). There is no output produced from Python, and an "Argument out of range" exception is generated when entering a command (which is echoed correctly) and then pressing return (which causes the exception).
Is there some limitation on what exe's can be run using a C# console? I cannot find any consoles written in C# that will run Python.
Thanks, Andrew
