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!
