Basic Coding Question: Exit Program Command?

[RockBlok]

Could anyone provide feedback on the preferred way to terminate a program?

A Google search suggested that there are 3 basic ways to terminate a program.

The three basic methods from Google are:

1. quit()

2. sys.exit("some sort of typed message here")

3. exit()

Thanks for the help!

Could anyone provide feedback on the preferred way to terminate a program?

It's a little vague question,i would say that preferred way is to think about a nice way to exit/terminate of program when write it.
Then many time there is no need to use quit(), exit(), sys.exit() at all,in some cases it may be useful.
A example,so here use a control variable q to exit the loop,also this exit program just bye return out of the function.

def file_deletion(): file_to_delete = input('File to delete: ') print(f'Deleting <{file_to_delete}>\n') input('Push enter to retun to menu') def file_creation(): pass def show_menu(): print ("\nExample menu") print ("-----------------") print ("1) File deletion") print ("2) File creation") print ("Q) Exit\n") def menu(): while True: show_menu() choice = input('Enter your choice: ').lower() if choice == '1': file_deletion() elif choice == '2': file_creation() elif choice == 'q': return else: print(f'Not a correct choice: <{choice}>,try again') if __name__ == '__main__': menu()

Output:
G:\div_code\ur_env λ python meny.py Example menu ----------------- 1) File deletion 2) File creation Q) Exit Enter your choice: car Not a correct choice: <car>,try again Example menu ----------------- 1) File deletion 2) File creation Q) Exit Enter your choice: 1 File to delete: foo.txt Deleting <foo.txt> Push enter to retun to menu Example menu ----------------- 1) File deletion 2) File creation Q) Exit Enter your choice: q G:\div_code\ur_env

Use sys.exit(), and read the documentation of this function first.

quit(), exit() and sys.exit() are the same, they all raise a SystemExit exception.
