I've changed a lot of the menus to now restart once an operation is done, rather than calling the function repeatably. Where appropriate, operations take you back to the previous menu.
I've also added an
Exitexception, which is called from anywhere, winds back to the main menu, is caught and then the program is cleanly exited.I've also added uses of
repeat_inputwhere I could, along with allowing it to take a function argument as an additional check on the input e.g. checking a number is greater than one. The function could still be improved to automatically convert the type (float to float, yes/no to boolean etc.)
