Selenium Python - Select a random radio button

In this tutorial, you will learn how to select a random radio button using Selenium Python.

To select a random radio button using Selenium Python,

  1. Find the required group of radio buttons.
  2. Use random library to randomly pick a radio button from the group.
  3. Then use click() method on the radio button, to select it.

Example

In this example, we shall consider loading the webpage at URL: /tmp/selenium/index-16.html. The contents of this HTML file is given below.

The webpage has a radio group with three radio buttons.

<html>
 <body>
  <h3>My Favourite Subject</h3>
  <form action="">
    <input type="radio" id="physics" name="fav_subject" value="Physics">
    <label for="physics">Physics</label><br>
    <input type="radio" id="mathematics" name="fav_subject" value="Mathematics">
    <label for="mathematics">Mathematics</label><br>
    <input type="radio" id="chemistry" name="fav_subject" value="Chemistry">
    <label for="chemistry">Chemistry</label>
  </form>
 </body>
</html>

In the following program, we initialize a webdriver, navigate to a specified URL, get the radio buttons with name="fav_subject", and then randomly select one of them.

We shall take screenshots before and after selecting a random radio button.

Python Program

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service as ChromeService
from selenium.webdriver.common.by import By
import random

# Setup chrome driver
service = ChromeService(executable_path=ChromeDriverManager().install())
driver = webdriver.Chrome(service=service)
driver.set_window_size(500, 400)

# Navigate to the url
driver.get('/tmp/selenium/index-16.html')

# Take a screenshot
driver.save_screenshot("screenshot-1.png")

# Get the radio button whose name="fav_subject"
radio_buttons = driver.find_elements(By.XPATH, "//input[@type='radio' and @name='fav_subject']")

# Randomly pick a radio button
radio_button = random.choice(radio_buttons)

# Click the radio button
radio_button.click()

# Take a screenshot
driver.save_screenshot("screenshot-2.png")

# Close the driver
driver.quit()
