Selenium Python – Select a radio button by value
In this tutorial, you will learn how to select a radio button by value in value attribute, in Selenium Python.
To select a radio button by value in Selenium Python, form the XPath expression that the element has the following two attribute value.
- type=”radio”
- value=”your_value”
The XPath expression would be as shown in the following.
"//input[@name='x' and @value='your_value']"You can use this XPath expression with find_element() method of driver object, and find the radio button with a specific value for value attribute.
radio_button = driver.find_element("//input[@name='x' and @value='your_value']")After finding the radio button, call click() method on the radio button WebElement object.
radio_button.click()Example
Consider the following HTML file index.html that has a radio group for selecting your favourite subject.
index.html
<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 specific URL (index.html) that is running on a local server, get the radio button with value equal to "Chemisty", and call click() method on the radio button element.
We shall take screenshots before and after selecting the 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
# 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('http://127.0.0.1:5500/index.html')
# Take a screenshot
driver.save_screenshot("screenshot-1.png")
# Get the radio button whose value="Chemistry"
radio_button = driver.find_element(By.XPATH, "//input[@type='radio' and @value='Chemistry']")
# Select the radio button
radio_button.click()
# Take a screenshot
driver.save_screenshot("screenshot-2.png")
# Close the driver
driver.quit()screenshot-1.png – Before selecting the radio button
screenshot-2.png – After selecting the radio button
