8. py2exe
   To package your Python program as an executable app (.exe file in Windows, similar executable on a Mac) that does not require Python to be installed on the client machine, check out py2exe for windows (tutorial here) or py2app for Macs (tutorial here). Alternatively, cx_freeze also does something similar but cross-platform for both Windows and Macs.
