Check if a page is completely loaded or not in Selenium web driver in Python

Hello programmers, in this tutorial we will see how to check if a page is completely loaded using the Selenium web driver in Python.

Selenium is a tool used for the automation of web browsers. It is controlled via a program that can be coded in various different languages such as Python, JavaScript, PHP, etc.

Here we will see a demo on how to use the Selenium web driver to check for a page is completely loaded or not in Python.

Installation

Download the selenium python using the following command in your command prompt.

pip install selenium

Basic Usage

For checking for a page is completely loaded or not, we use the concept of waits. Check out the Selenium Wait in Python blog for more details.

An implicit wait is used to wait for a certain time for a particular element that is not available immediately whereas the explicit wait is used to meet a certain condition to occur.
For checking the page is completely loaded, we use explicit wait conditions to check for it.

Before running the code, we need to install the chrome driver and executable file path location to the system path.

Checking if a page is completely loaded or not using Selenium in Python

Given below is the illustration of using the explicit wait function to check for the load of the page.

#Importing necessary libraries
from selenium import webdriver 
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

#wait for page load function
def seleniumPageLoad():
    #creating a webdriver object
    driver = webdriver.Chrome(executable_path='C:/path/to/dir/chromedriver.exe')
    driver.maximize_window() #maximize window size
    driver.get("https://www.codespeedy.com/") #opening the url
    try:
        ele = WebDriverWait(driver, 10).until( #using explicit wait for 10 seconds
        EC.presence_of_element_located((By.CSS_SELECTOR, "h2")) #checking for the element with 'h2'as its CSS
    )
        print("Page is loaded within 10 seconds.")
    except:
        print("Timeout Exception: Page did not load within 10 seconds.")

#driver
if __name__ == "__main__":
    seleniumPageLoad() #call the function

Output

Page is loaded within 10 seconds.

Explanation
Within the function, we use the ‘.get()’ method to open the URL and then we check for a particular element presence using the explicit wait condition within the ‘try’ block. If the page loads within 10 seconds of the given time, the ‘page is loaded’ statement is printed, else the timeout exception error occurs.
