Code exiting issue in Python 2.7

Question

I am working on ROS and I have written a code in Python 2.7 and in the menu I am asking the user to select either option 1 or 2. After the task is accomplished, when I press Ctrl+c, instead of exiting the code, it displays the menu again, instead of exiting. Here again if I choose between 1 or 2, it keeps printing the menu again and again.

What changes in the code would be suggested in order to exit the code as soon as I press Ctrl+c instead of displaying the menu again and again?

The code and the screen shot of the problem are below:

if __name__=='__main__':    
  while(True):  
    try:
        print "***********"
        print "1. Continuous"
        print "2. Single Step"
        print "***********"
        try:
            choice = int(raw_input('Choose a number between 1 & 2: '))
            number = choice
            move_group_python_interface()

        except ValueError:
            print "ERROR! Choose a number between 1 and 2"

    except rospy.ROSInterruptException:
    break

Answer 1

I found the issue. The problem was with while(True):. Once I comment it out, it exits without any problem.
