How to stop running python

Python is a program that interprets and runs. If the program enters an infinite loop or other exceptions, the program will not end normally. Although the python program will not cause the system to enter an abnormal state that is difficult to recover like the exe program, it will make the python interpreter unable to continue working, especially when using the command line mode. Then we need to consider the termination of the python program.

Method 1: Use sys.exit(0) to terminate the program normally. As you can see from the figure, the shell operation will not be affected after the program terminates.

Method 2: Use os._exit(0) to close the entire shell. As you can see from the picture, the entire shell restarts after calling sys._exit(0) (RESTART Shell).
