In this exercise, you$$ll modify the Future Value program so the user can$$t cause the program to crash by entering an invalid int or float value. $1.$ In IDLE, open the future$\_$value.py file that$$s in this folder: python$/$exercises$/$ch$08$

$2.$ Review the code and study the get$\_$number$()$ and get$\_$integer$()$ functions. Note that they receive three arguments: the prompt for a user entry, the low value that the entry must be greater than, and the high value that the entry must be less than or equal to$.$ Then, review the calling statements in the main$()$ function and note how these functions are used.

$3.$ Test the program. Note that you can cause the program to crash by entering values that can$$t be converted to float and int values.

$4.$ Add exception handling to the get$\_$number$()$ and get$\_$integer$()$ functions so the user has to enter valid float and int values. Then, test these changes to make sure the exception handling and the data validation work correctly.
