Hi Everyone, I have just received a project in order to build a python program for a safari park including being tickets (adding discounts), keeping note of their time (one car is maximum allowed for two hours ) and making sure everything works well, like the safety of the lions when they visit a lion, etc. Like I need to make sure that all the windows of the passengers are closed when they visit them. Any suggestions on how I can do so and an example code will be really appreciated.
