An application to test the given page is found or not on the server using Python

Last Updated : 29 Dec, 2020

In this article, we are going to write scripts to test whether the given page is found on the server or not with a GUI application. We need to Install Urllib Module to carry out this operation. Type this command in your terminal.

pip install urllib

Approach:

Import urllib module.
Read URL with urllib.request.urlopen().
Check if Read URL gives any exception.

Implementation:

Python3

# import module 
from urllib.request import urlopen, URLError, HTTPError 
  
# exception handling to 
# catch URL error 
try: 
    html = urlopen("https://www.geeksforgeeks.org/") 
  
except URLError as e: 
    print("Server not found!") 
  
except HTTPError as e: 
    print("HTTP error") 
  
else: 
    print("Server found") 

Output:

Server found

Application to test the given page is found or not on the server with Tkinter: This Script combines the implementation above with a GUI.

Python3

# import modules 
from tkinter import *
from urllib.request import urlopen, URLError 
  
# user defined funtion 
def URL_check(): 
    try: 
        html = urlopen(str(e1.get())) 
    except URLError as e: 
        res = "Server not found!"
    else: 
        res = "Server found"
    result.set(res) 
  
  
# object of tkinter 
# and background set to light grey 
master = Tk() 
master.configure(bg='light grey') 
  
# Variable Classes in tkinter 
result = StringVar() 
  
  
# Creating label for each information 
  
# name using widget Label 
Label(master, text="Enter URL : ", bg="light grey").grid(row=1, sticky=W) 
Label(master, text="Status :", bg="light grey").grid(row=3, sticky=W) 
  
# Creating lebel for class variable 
  
# name using widget Entry 
Label(master, text="", textvariable=result, 
      bg="light grey").grid(row=3, column=1, sticky=W) 
  
  
e1 = Entry(master, width=50) 
e1.grid(row=1, column=1) 
  
# creating a button using the widget 
b = Button(master, text="Check", command=URL_check, bg="white") 
b.grid(row=1, column=2, columnspan=2, rowspan=2, padx=5, pady=5,) 
  
mainloop()
