Simple calculation using datetime - mapypy - Feb-06-2021

Hi, How can i calculate age using date time without hardcoding current year? The way I want to solve and validate is as follows:

from datetime import date

def get_age(birth_year):
    """
    returns the age based on current year
    """
    current_year = date.today().year
    
    return

validate age:

assertion('12a', get_age(1950), 71)
assertion('12b', get_age(1990), 31)
assertion('12c', get_age(2020), 1)

In fact, the way you try to do this (with only the birthyear), will not always give the exact result. Because it will basically look to the age the subject will reach the particular year. But besides of that, the following code would do the trick right?

def get_age(birth_year):
    """
    returns the age based on current year
    """
    diff = date.today().year - birth_year
    return diff

To get the exact date you should also use the month and day in your calculation. You can simply calculate a datetime.date object with another datetime.date object. It will return a timedelta object.
