I use the following code in the python command line interpreter, but the window doesn't respond.

import pyglet
window = pyglet.window.Window()

A white window with python icon into left-upper corner appears but then it basically hangs. Windows task manager shows that this window is not responding. However the Python command prompt works well. No errors or warning messages get displayed.

    \$\begingroup\$ you probably need an event loop that checks for input/window updates \$\endgroup\$

You need to add an event loop for your window. The following code is directly from a pyglet quickstart tutorial.

You basically need a function that gets called periodically. After that you can then just ask pyglet to run the application. Here's a basic draw function:

@window.event
def on_draw():
    window.clear()

and then just call pyglet.app.run() to start the app.
