I trying this: link

C#:

private void Form1_Load(object sender, EventArgs e)
{
    var ipy = Python.CreateRuntime();
    dynamic test = ipy.UseFile(@"C:\Users\Admin\Desktop\Test.py");
    textBox1.Text = test.Simple();
}

Python:

def Simple():
    print "Hello from Python"

No error, when I run it, the textbox remain blank. What I doing wrong?

Don't know Python, but should not you return something from `Simple` function instead of just `print` ? — Alexei Levenkov, Nov 15 '12 at 23:46
@AlexeiLevenkov That is true, the link that he got the example from is printing to a console window. He should be using `return "Hello from Python"` instead. — matthewr, Nov 15 '12 at 23:47
yes guys you absolutely right... I though c# take the output of cmd and pass it to c#... Thanks for help — a1204773, Nov 15 '12 at 23:50
Converted my comment into answer. @KirkWoll, I don't think it is dup as the linked question is talking about how to actually do that, but not why particular method Python returns nothing. — Alexei Levenkov, Nov 15 '12 at 23:55
@AlexeiLevenkov, I guess you're right. I was just thrown by the fact that when I tried to fix the spelling error in the OP's title, it wouldn't let me because of the existing question. :) — Kirk Woll, Nov 16 '12 at 00:10

Your Simple function does not return anything, it just prints output to console with print. Something like return "Hello from Python" should give you results you want.

Side note: you may be able to intercept console output, but it would probably not what you are interested in.
