You have answer to your initial question - use try...except.
How to implement is another story. You haven't given enough information to understand what you want to accomplish. As it smells like homework I would just generalise: one can have validation function which checks user input with try...except and returns only valid value. One can apply this function to whatever number of user inputs and assign result to whatever variable.
