This problem aims at letting you practice using the conditionals if (and the while loop, but not necessary), together with string slicing. You are asked to write a program that calculates the Life Path Number of a person. The Life Path is the sum of the birth date. This number represents who you are at birth and the native traits that you will carry with you through life. The Life Path number can be calculated by four steps. (1) Reduce your birth Year to a single digit by iteratively summing up each digital, and obtain num_year. (2) Reduce your birth Month to a single digit by iteratively summing up each digital, and obtain num_month. (3) Reduce your birth Day to a single digit by iteratively summing up each digital, and obtain num_day. (4) Sum up num_year ,num_month , and num_day as num_total, and reduce num_total to a single digit by iteratively summing up each digital. Note that in your output, the birthday is required to follow the format yyyy/mm/dd. In other words, year is 4 digitals, month is 2 digital, and day is 2 digital.
For example, assume your birthday is 1997/12/29, your Life Path Number is
num_year: 1 + 9 + 9 + 7 = 26, 2 + 6 = 8 num_month: 1 + 2 = 3 num_day: 2 + 9 = 11, 1 + 1 = 2 num_total = num_year + num_month + num_day: 8 + 3 + 2 = 13 life_path_number = 1 + 3 = 4
