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
