How Can I Determine the Day of the Week from a Date in Python?

Determining Weekday from a Date

Given a datetime object, the question arises as to how we can ascertain its corresponding weekday. In other words, how do we determine whether it's Sunday, Monday, and so forth?

To answer this, Python provides the weekday() method for datetime objects. Let's explore its usage:

import datetime

today = datetime.datetime(2017, 10, 20)
weekday_num = today.weekday()  # Integer representing the weekday

The integer returned by weekday() corresponds to the weekday, with Monday being 0 and Sunday being 6. In this example, as today's date is Friday, weekday_num would be 6.

Here's an example using the current date:

import datetime

today = datetime.datetime.today()
weekday_num = today.weekday()

The weekday_num variable will contain an integer representing the current day of the week (e.g., 4 for Thursday).
