Write a program, with comments, to do the following: + a. ask the user to enter a positive integer (digits only) n. b. check the value entered to see if it corresponds to a positive integer. c. if the user entered a positive integer do the following: if 0 80 calculate 1.2 (0.2*n) then print n and the calculated result with a suitable message. 19 d. otherwise, print the message you did not enter a valid input!

Working on this program in python 3.7: a year in the modern gregorian calendar consists of 365 days. in reality, the earth takes longer to rotate around the sun. to account for the difference in time, every 4 years, a leap year takes place. a leap year is when a year has 366 days: an extra day, february 29th. the requirements for a given year to be a leap year are: 1) the year must be divisible by 42) if the year is a century year (1700, 1800, the year must be evenly divisible by 400some example leap years are 1600, 1712, and 2016.write a program that takes in a year and determines whether that year is a leap year.ex: if the input is 1712, the output is: 1712 is a leap year. ex: if the input is 1913, the output is: 1913 is not a leap year. your program must define and call the function isleapyear(useryear). the function should return true if the input year is a leap year and false otherwise.
