Return Number of Week of datetime Object in Python (Example Code)

In this tutorial, you’ll learn how to get the week number of a datetime object in Python programming.

Example Data

First, we have to load the datetime module, as you can see below:

import datetime                                     # Import datetime

Example: Return the Week Number of datetime

Next, we create a new datetime object as a basis for the example.

date_x = datetime.datetime(2020, 9, 12, 7, 35, 18)  # Example date
print(date_x)                                       # Print date
# 2020-09-12 07:35:18

Since the isocalendar function works with a tuple containing year, week number, and day of week, we structure our datetime object the same way and can afterwards define the index position we want to be returned:

yr, wn, wd = date_x.isocalendar()                   # Using isocalendar function
print(wn)                                           # Printing number of week
# 37

In our case, we want to know the week number, so we simply print ‘wn’.
