if$-1.$py program $$ using the grade.py program as a model:

Write a program that asks the user to enter a number of pennies in a jar $($an integer$).$

The program should give an appropriate message, and end if the user provides unexpected input $($letters$,$ negative numbers, etc$).$ Hint: adapt the validation code from the lesson, slide $15.$

If the user input passes validation, the program should use a conditional logic block to give them one of these three custom messages, depending on the number of pennies they enter:

Messages to the user: You have less than a dollar OR You have more than a dollar OR$$ You have exactly one dollar.

End with a sentence, telling the user how much their pennies are worth in dollars and cents.

Remember to include two types of comments in your programs $("""$doc string at the top""" and # short thru$-$out$)$ & customize$/$ improve how the program looks and acts, through a process of testing$$

Run several times to show ALL the possible options.
