It is not possible to put restrictions on what will be accepted by input(). If the user enters
   delete('*.*')
at an input prompt then the deletion will proceed. Nothing you can do about it as long as you use input() without the 's' argument.
So if you care about what the user might enter then do not use input(). Or use the 's' option and validate the form of the values before converting from character to numeric. Or use input() and check the input before using it.
