write a program to ask user about the date(year, month and day), then pass these year month and day as arguments to a function calcDay that return the day of the year.
Day of the year: 175
- You need consider leap years and non leap years, in order to do easier calculation, you may create a list to contain all the days in each month. If it is a leap year, then mo = [31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31], otherwise, mo = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
- % is getting remainder of the division, so we can use it to calculate the leap year or not, for example year 2016 is a leap year because 2016 % 4 == 0
- We could use for i in range() to get the index of every previous month and add them together. Or we could use sum(list) to calculate the total number in the list or slice of the list, for example: if there’s a list a = [1,2,3,4,5,6,7], then sum(a[:5]) will add 1,2,3,4,5 together
