Test the given page is found or not on the server Using Python

  • Last Updated : 21 Aug, 2021

In this article, we are going to write a Python script to test the given page is found or not on the server. We will see various methods to do the same.

Method 1: Using Urllib.

Urllib is a package that allows you to access the webpage with the program.

Installation:

pip install urllib

Approach:

  • Import module
  • Pass the URL in urllib.request() reading URLs
  • Now check with urllib.error containing the exceptions raised by urllib.request

Implementation:

Python3




# import module
from urllib.request import urlopen
from urllib.error import *
 
# try block to read URL
try:
    html = urlopen("https://www.geeksforgeeks.org/")
     
# except block to catch
# exception
# and identify error
except HTTPError as e:
    print("HTTP error", e)
     
except URLError as e:
    print("Opps ! Page not found!", e)
 
else:
    print('Yeah !  found ')


Output:

Yeah !  found

Method 2: Using requests

Request allows you to send HTTP/1.1 requests extremely easily. This module also does not come built-in with Python. To install this type the below command in the terminal.

Installation:

pip install requests

Approach:

  • Import module
  • Pass the Url into requests.head()
  • If response.status_code == 200 then server is up
  • if response.status_code == 404 then server in down

Implementation:

Python3




# import module
import requests
 
# create a function
# pass the url
def url_ok(url):
     
    # exception block
    try:
       
        # pass the url into
        # request.hear
        response = requests.head(url)
         
        # check the status code
        if response.status_code == 200:
            return True
        else:
            return False
    except requests.ConnectionError as e:
        return e
 
# driven code
url_ok(url)


Output:

True
