    It should be like that. If there is only one class then use find_element(By.CLASS_NAME," #what is class name"). However, button has 2 different class so u need to use CSS_SELECTOR instead CLASS_NAME. Finally fyi "class name" doesn’t work in find_elements as an argument.

    Button = driver.find_element(By.CSS_SELECTOR,".css-v84xw-NakedButton .eml2css7")

    For more details you can take look on Selenium Doc.

    There are multiple ways to find the elements. In your case class name has 2 different values so it is better to use CSS_SELECTOR You can select by CLASS_NAME if you want to pass only one word of a particular tag.

    buttons = driver.find_element(By.CSS_SELECTOR,"button.css-v84xw-NakedButton.eml2css7")

    here button is the intended tag that we want to select and css-v84xw-NakedButton.eml2css7 is class name so all values in the class are concatenated with a dot (.)
    The below code snippet selects all the rooms and expand those.

    from selenium import webdriver
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
import time

def rooms():
    driver = webdriver.Chrome()
    driver.get("https://www.qantas.com/hotels/properties/18482?adults=2&checkIn=2024-04-16&checkOut=2024-04-17&children=0&infants=0#view-rooms")
    driver.implicitly_wait(5)

    # If you want to use xpath then uncomment below line
    # buttons = driver.find_elements(By.XPATH, "//button[contains(@data-testid,'expand-offer-summary')]")
    # # If you want to use classname with a single value then uncomment below line. I took the first value here as it is also returning same output
    # buttons = driver.find_element(By.CLASS_NAME,"css-v84xw-NakedButton")
    buttons = driver.find_element(By.CSS_SELECTOR,"button.css-v84xw-NakedButton.eml2css7")
    for btn in buttons:
        driver.execute_script("arguments[0].scrollIntoView();", btn)
        time.sleep(1)
        btn.click()

    # Taking page source at the end so that all the room details were expanded.
    content = driver.page_source
    soup = BeautifulSoup(content,'html.parser')
    driver.quit()

rooms()
