-> Error handling in python:

    for ex:
        while True:
            try:
                age = int(input('what is your age? '))
                print(age)
            except:
                print('please enter a number')
            else:
                print('thank you')
                break


    for ex:
        def sum(num1, num2):
            try:
                return num1 + num2
            except TypeError as err:
                print(f'please enter a number {err}')


        print(sum(1, '2'))

    for ex:
        def sum(num1, num2):
            try:
                return num1/num2
            except (TypeError, ZeroDivisionError):
                print(f'please enter a number {err}')


        print(sum(1, '2'))

-> How to throw your own error?

    for ex:
        while True:
            try:
                age = int(input('what is your age? '))
                10/age
                raise ValueError('hey cut it out')
            except ValueError:
                print('please enter a valid number')
            except ZeroDivisionError:
                print('please enter age higher than 0')
                break
            else:
                print('thank you')
                break
            finally:
                print('ok, I\'m finally done')
            print('can you hear me?')
