Environment

• Pythonnet version: 2.2.2 (.NET 4, x64)
• Python version: 3.5
• Operating System: Windows 10

Details

Python is embedded in my .NET application using pythonnet. I found the output of the print statement in a python script is not showing on the screen until a "sys.stdout.flush()" called. I don't known how to redirect sys.stdout in .NET.
In order to call the flush() method directly in .NET, I tried

dynamicsys=PythonEngine.ImportModule("sys");varstdout=sys.GetAttr("stdout");// returns None

and both sys.stdout and the variable stdout returned are None here.

In python, I tried

importsysprint(getattr(sys,'stdout'))

and it outputs a_io.TextIOWrapper object.

Why sys.stdout returned null here? How to make the output of python print statement show automatically?

Thanks.
