Stopped process is still running

[pawlaczkaj]

I have got a menu written in Python:

if __name__ == '__main__':
    print_menu()    # display the menu
    choice = input("Type number")

    if choice == 1:
        function1()    # function, which calls the other functions
    if choice == 2:
        function2()

I had run function1 and before it reached the end I had stopped the script in terminal with Ctrl+C (I use Ubuntu 16.04). After it I want to check function2, but when I am running the script with menu, the menu is not displayed and it goes immediately to function1. It looks like the function1 is running whole the time, but when I check processes with ps ax there is not my script.

How can I terminate running function1?

It depends on what is in function1. Are you using subprocess or multiprocessing to start a separate process? If you are using Python3.x, neither option will be run.

Function1 and function2 are collision avoidance algorithms which are sending to the simulator. They control the robot's moving as long as it reachs the goal.
I use only functions with loops. I am new in Python, so I don't know subprocess and multiprocessing.
I have the same problem when I use Python2.x and Python3.x too.

Then you have no process that continues after the program exits (Ctrl+c kills everything).

If Ctrl+c kills everything, why after new running script, it doesn't display menu, but it runs function1?

After Ctrl-C, the program should print an exception traceback

Output:
Traceback (most recent call last):
  File XXX, line XXX, in <module>
    XXX
KeyboardInterrupt

If it doesn't do that, there is another error somewhere.

But I have got this output. I think there is another problem.
Ctrl+c should "reset" the whole program and come back to start. Right?
When I run the same scripts, which are called in the menu, without the menu's script and I use ctrl+c everything is ok. I mean programm stop and when I run it again, it starts from the beginning. So in that case should I use subprocess or multiprocessing?

[Gribouillis]

If you have this output, it means that the program exited. If the program does not start other processes or threads, there is nothing left of this program's execution. I don't understand your description with the menu: which menu are you talking about? Are you running the script from an IDE or from a terminal? Try to run the program from an ordinary terminal.

I have got menu.py with code from my first post. Also I have got algorithms' scripts: algorithm1.py and algorithm2.py. They are called in menu.py in function1 and function2.
At the beginning of my coding I wrote algorithms' scripts and I checked them. Everything worked as it should - after ctrl+c script ends and when I run it again, it starts from the script's first line. But when I test menu.py, I have a problem mentioned in posts - after ctrl+c script ends and when I run it again, it starts from the script's middle (it goes to the algorithm that was interrupted).
I run my scripts from terminal.

I think it can be debugged only if you post the complete code, or a link to the code.
