To detect a script exit, we can use the built-in the atexit library of Python. Running python scripts in an interactive mode in Python: You need to be very careful while using the interactive mode. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview … Any optional arguments that are to be passed to func must be passed as arguments to register().It is possible to register the same function and arguments more than once.
