Generate Date Range in Python

Introduction

In Python, the datetime module provides classes for working with dates and times. One common task is to create a list of dates between two given dates. In this challenge, you will create a function that takes two dates as input and returns a list of all the dates between them.

Date Range

Write a Python function called daterange(start, end) that takes two datetime.date objects as arguments and returns a list of all the dates between them. The list should include the start date but not the end date.

To solve this problem, you can follow these steps:

1. Use datetime.timedelta.days to get the number of days between start and end.
2. Use int() to convert the result to an integer and range() to iterate over each day.
3. Use a list comprehension and datetime.timedelta to create a list of datetime.date objects.

from datetime import timedelta, date

def daterange(start, end):
  return [start + timedelta(n) for n in range(int((end - start).days))]

from datetime import date

daterange(date(2020, 10, 1), date(2020, 10, 5))
## [date(2020, 10, 1), date(2020, 10, 2), date(2020, 10, 3), date(2020, 10, 4)]

Summary

In this challenge, you have learned how to create a list of dates between two given dates using the datetime module in Python. You can use this function to solve a variety of problems, such as calculating the number of days between two dates or generating a list of dates for a given month or year.
