N this lab, you add the input and output statements to a partially completed Python program. When completed, the user should be able to enter a year, a month, and a day. The program then determines if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31.

Instructions

Notice that variables have been declared for you.

Write input statements to retrieve a year, a month, and a day from the user.

Include the print statements to output the following:

month/day/year is a valid date.
or

month/day/year is an invalid date.
Execute the program entering the following input:

month = 5, day = 32 year = 2014
Execute the program entering the following input:

month = 9 day = 21 year = 2002
