XKCD is a popular web comic covering humor, science, and geek culture. The comic is known for its witty jokes and references to culture and science. We can use the XKCD API and Python's request and pillow libraries to download comics. In this article, we will use Python to download XKCD comics.
XKCD provides an open API, allowing developers to use the API to access comics. To use the API, we need to send an HTTP GET request to the URL - `http://xkcd.com/info.0.json`. The request returns a JSON object containing information about the latest XKCD comics.
To use Python to download XKCD comics, you need to install the request module and the pillow library. The requests library allows us to make HTTP requests to the XKCD API, while the Pillow library allows us to manipulate images. Enter the following commands to install the requests and Pillow libraries.
pip install requests pip install Pillow
The code imports two Python modules − requests and PIL.Image. The requests module is used to make HTTP requests, while the PIL.The image module is used to manipulate and save images. The io module is imported to work with bytes objects, particularly to open images from the XKCD API.
import requests import io from PIL import Image
The download_comic function takes an ID number as an argument and returns the comic object as a pillow image.
def download_comic(comic_id): # Construct the URL for the XKCD API url = f'http://xkcd.com/{comic_id}/info.0.json' # Make an HTTP GET request to the XKCD API response = requests.get(url) # Parse the JSON response data = response.json() # Extract the image URL from the JSON data image_url = data['img'] # Make an HTTP GET request to the image URL response = requests.get(image_url) # Open the image using Pillow image = Image.open(BytesIO(response.content # Return the image as a Pillow object return image
The function download_all_comics takes the starting id and ending id of the comics to download all the comics between the starting and the ending id.
def download_all_comics(start_id, end_id): for comic_id in range(start_id, end_id + 1): try: # Download the comic image = download_comic(comic_id) # Save the image to a file filename = f'{comic_id}.png' image.save(filename, 'PNG') print(f'Saved {filename}') except Exception as e: print(f'Error downloading comic {comic_id}: {e}')
Call the download all comics method with the starting and ending id of the comics to be downloaded.
download_all_comics(1, 10)
The complete code is written below −
import requests import io from PIL import Image # Define a function to download a single XKCD comic def download_comic(comic_id): # Construct the URL for the XKCD API url = f'https://xkcd.com/{comic_id}/info.0.json' # Make an HTTP GET request to the XKCD API response = requests.get(url) # Parse the JSON response data = response.json() # Extract the image URL from the data dictionary image_url = data['img'] # Make an HTTP GET request to the image URL response = requests.get(image_url) # Open the image using Pillow image = Image.open(io.BytesIO(response.content)) # Return the image as a Pillow object return image # Define a function to download all XKCD comics def download_all_comics(start_id, end_id): for comic_id in range(start_id, end_id + 1): try: # Download the comic image = download_comic(comic_id) # Save the image to a file filename = f'{comic_id}.png' image.save(filename, 'PNG') print(f'Saved {filename}') except Exception as e: print(f'Error downloading comic {comic_id}: {e}') # Call the download_all_comics function to download the first 10 XKCD comics download_all_comics(1, 10)

In this article, we discussed how to download XKCD comics using the request and pillow libraries in Python. XKCD provides an API to access comics. The request module sends an HTTP request to the API URL and receives the comic data list as an object. The received data can then be used to download comics. You can use this code to download your favorite XKCD comics or build your own XKCD related projects.
