public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

    private void button3_Click(object sender, EventArgs e)
    {
        try
        {
            var strExpression = @"

import sys
sys.stdout=my.write
print 'ABC'
";
var engine = Python.CreateEngine();
var scope = engine.CreateScope();
var sourceCode = engine.CreateScriptSourceFromString(strExpression);
scope.SetVariable("my", this);
var actual = sourceCode.Execute(scope);
textBox1.Text += actual;
}
catch (System.Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
 public void write(string s)
{
textBox1.Text += s;
}
}<code>

But Exception says there is not write.

Where is wrong? Thanks!
