Question

Assuming that students graduate on-time in four years, Use the Design Recipe to define a function matriculation_year which should consume the year of graduation (as an int), and which returns the year the student must start school in order to graduate in the given year. Include a Docstring.

I'm doing this on Python.

Answer 1

def matriculation_year(year):
    """
    This function calculates the year student must start school in order to graduate in the given year
    :param year: Year of graduation
    :return: the year the student must start school in order to graduate in the given year
    """
    return year - 4
