Collection of Data for Dates

Part 1: Computing the number of days in a month write a function called "days_in_month" in python 3 that takes two integers: a year and a month. The function should return the number of days in that month. assume that both inputs are valid the month input is a number between 1 and 12 and the year input is a number between 0000 and yyyy. You do not need to check that the inputs are within the proper ranges. You can assume that any function that calls this one will already have checked that. Make sure you account for leap year: #my first attempt.... def days_in_month(year, month): """ Inputs: year - an integer between [login to view URL] and [login to view URL] representing the year month - an integer between 1 and 12 representing the month Returns: The number of days in the input month. """ if (month == 4) or (month == 6) or (month == 9) or (month == 11): days_in_month = 30 if (month == 1) or (month == 3) or (month == 5) or (month == 7)or (month == 8) or (month == 10) or (month == 12): days_in_month = 31 if (month == 2): bool isLeapyear = (year % 4 == 0) and (year % 100 != 0) or (year % 400 == 0) #boolean formula for Leap year if(isLeapyear): days_in_month = 29 else: days_in_month = 28 return (days_in_month) One way in which to determine the number of days in a month is to subtract the first of the given month from the first of the next month. The result should be the number of days in the given month. Part 2: Checking if a date is valid write another function called "is_valid_date" that takes three integers: a year, a month, and a day. The function should return "True" if that date is valid and 'False" otherwise. This function should not assume that the inputs are valid. Rather, this function should check that all three inputs combine to form a valid date, with a year between [login to view URL] [login to view URL] and [login to view URL], a month between 1 and 12, and a day between 1 and the number of days in the given month. Notice that the function days_in_month that you wrote for Part 1 will be useful here! Part 3: Computing the number of days between two dates Now that we have a way to check if a given date is valid, you will write a function called days_between that takes six integers (year1, month1, day1, year2, month2, day2) and returns the number of days from an earlier date (year1-month1-day1) to a later date (year2-month2-day2). If either date is invalid, the function should return 0. Notice that you already wrote a function to determine if a date is valid or not! If the second date is earlier than the first date, the function should also return 0. Be sure to first check that all of the inputs are valid. Do not repeat code. Make sure you reuse things that you have already written. Make sure to check the cases where the function is supposed to return 0. Part 4: Calculating a person's age in days Finally, you will write a function called "age_in_days" that takes three integers as input: the year, month, and day of a persons birthday. The function should return that person's age in days as of today. The function should return 0 if the input date is invalid (remember you have a function to check that!). The function should also return 0 if the input date is in the future.
