The hackAffine() function begins on line 25 and contains the code for decryption. It starts by printing some instructions for the user:

25. def hackAffine(message):

26. print('Hacking...')

27.

28. # Python programs can be stopped at any time by pressing Ctrl-C (on

29. # Windows) or Ctrl-D (on macOS and Linux):

30. print('(Press Ctrl-C or Ctrl-D to quit at any time.)')

The decryption process can take a while, so if the user wants to exit the program early, they can press ctrl-C (on Windows) or ctrl-D (on macOS and Linux).

Before we continue with the rest of the code, you need to learn about the exponent operator.
