Get outputs of IronPython live in C#(WPF)?

Juliette 1

I am developing an app in C# WPF. The app should call Python scripts. I use IronPython for this. Unfortunately I have some difficulties. I don't get the prints from Python displayed live.

Is it possible to display the output of Print live in TextBox(like in Python IDE)?

namespace PythonCall  
{  
    public class MainViewModel : BaseViewModel  
    {  
        public string PyOutput { get; set; }  
        public RelayCommand Cmd { get => new RelayCommand(Exec); }  
        private void Exec(object parameter)  
        {  
            switch (parameter.ToString())  
            {  
                case "Start":  
                    try  
                    {  
                        ScriptConfig();  
                        OnPropertyChanged(nameof(PyOutput));  
                    }  
                    catch (Exception ex)  
                    {  
                        MessageBox.Show(ex.Message);  
                    }  
                    break;  
  
                default:  
                    break;  
            }  
        }  
        public void ScriptConfig()  
        {  
             
        }  
    }  
}

The variable "PyOutput" is prepared for this and this is the binding to TextBox.

Any help is appreciated

Did you check (using Debugger) the value of PyOutput after the first and second 'PyOutput = ...'? By the way, probably you can use "+=" instead of "=" in the second case.

The first value of PyOutput is 19 and the second is 8. As far as is ok but I want to assign the string from the "Print" command also to the variable "" and display it in UI.
Showing for example string "Calculation is done" should be done in run and not when the function has been executed.

@Viorel I use the following Python script:

import sys  
import time  
  
class calculator:  
    def add(self, x, y):  
        print("Calculation is done.")  
        return x + y  
  
    def increment(self, x):  
        x += 1;  
        print("variable was incremented")  
        return x;

If you are using the binding correctly, then try calling OnPropertyChanged(nameof(PyOutput)) after each modification of PyOutput.

I use the binding correctly and I call OnPropertyChanged(nameof(PyOutput)). The variable PyOutput also shows the correct return value from the functions.

But my question is how to assign the strings from the Prints command also to PyOutput?
