Step 6 (actually writing the day-of-year function): Write a function called day_of_year that takes three integer parameters: a month (1-12), a day (1-31), and a year (any year is possible). This function should return the day of year (1-366) that this date occurs on. Here's how you do it. You need to two pieces of information: first, figure out whether the year is a leap year or not (hint---call your is_leap function on the year and capture the return value). Next, get the appropriate magic_month value for the month (hint---call your magic_month function on the month and capture the return value). The formula for finding the day of the year is quite simple: The day of the year is the magic_month number plus the day of the month. If this year is a leap year and the month is March or later, add one to this result. The definition line of this function should look like this def day_of year(month, day, year): Example: Suppose we call day of year(7, 29, 2019) to calculate the day of the year for July 29, 2019. 2019 is not a leap year, and the magic_month number for July (month #7) is 181. So the day of the year here is 181 +29, which is 210. Example 2: Suppose we call day_of_year(4, 11, 2016) to calculate the day of the year for April 11, 2016. 2016 is a leap year, and the magic_month number for April (month #4) is 90. So the day of the year here is 90 + 11 + 1, which is 102. Step 6A: Test your day_of_year function.
