Python Multi-threading and concurrency: Concurrent HTTP requests with threads

Python Multi-threading: Exercise-7 with Solution

Write a Python program that performs concurrent HTTP requests using threads.

Sample Solution:

Python Code:

import requests
import threading
def make_request(url):
    response = requests.get(url)
    print(f"Response from {url}: {response.status_code}")
# List of URLs to make requests to
urls = [
# Create and start threads for each URL
threads = []
for url in urls:
    thread = threading.Thread(target=make_request, args=(url,))
# Wait for all threads to finish
for thread in threads:

Sample Output:

Response from https://www.google.com: 200
Response from https://www.wikipedia.org: 200
Response from https://www.python.org: 200
Response from https://www.example.com: 200


In the above exercise,

  • The "make_request()" function sends an HTTP GET request to a given URL using the requests library. The function prints the URL and the response status code.
  • The program creates a list of URLs you want to request. It then iterates over the URLs, creates a thread for each URL using threading.Thread, and starts the thread by calling its start method. The threads are stored in a list for later joining.
  • After starting all the threads, the program uses a loop to join each thread using the join method. This ensures that the program waits for all threads to finish before proceeding.
  • Finally, the program prints a message indicating that all requests have been fulfilled.
