I am getting the output:

ankit@ubuntu:~/Desktop$ python controlpt.py

<brisa.core.reactors.glib2.GLib2Reactor object at 0x88c3e0c>
hello
hell

It is not going to the line c = create_control_point. why is that? please guide me in removing this error.

I am not familiar with this 'brisa' library. I would gather that, for some reason, the ControlPoint constructor is exiting the entire program using sys.exit() (or is calling some equivalent C code).

Run the program on the command-line, like this:

$ python
>>> import controlpt
>>> controlpt.main()

Then you should be able to see if it is actually quitting the whole process. If it dumps you back to the >>> prompt, then I don't know what's going on. But if it quits Python entirely, it means that that ControlPoint constructor is quitting.
