Python Date and Time Manipulation

Introduction

In Python, the datetime module provides classes for working with dates and times. One of the classes in this module is date, which represents a date (year, month, day) and provides various methods to work with dates. Another class is timedelta, which represents a duration or difference between two dates or times.

Days Ago

Your task is to write a function called days_ago(n) that takes an integer n as an argument and returns the date of n days ago from today.

To solve this problem, you need to use the date class from the datetime module to get the current date and the timedelta class to subtract n days from the current date.

from datetime import timedelta, date

def days_ago(n):
  return date.today() - timedelta(n)

days_ago(5) ## date(2020, 10, 23)

Summary

In this challenge, you learned how to use the date and timedelta classes from the datetime module to calculate the date of n days ago from today. This is a useful skill when working with dates and times in Python.
