Using Python 3: Write a function name leap_year that asks the user to enter the month (letting the user enter an integer in the range of 1 through 12) and the year. The program should then display the number of day in that month. Use the following criteria to identify the leap years: 1. Determine whether the year is divisible by 100. If it is, then it is a leap year if and only if it is divisible by 400. For example, 2000 is a leap year but 2100 is not. 2. If the year is not divisible by 100, then it is a leap year if and if only it is divisible by 4. For example, 2008 I a leap year but 2009 is not.
