Selenium click on button by class name

Hi I am new at using selenium and I am automating a certain process for my work. I have successfully been able to fill in forms and click on several buttons but when verifying my MFA, the button to verify doesn't work.

HTML for button:

<button class = "btn blue trustdevice trustbtn" onclick="updateTrustDevice(true)"> 
<span class ="loadwithbtn" style="display: none;"></span> 
<span class "waittext">Trust</span> 
</button>

My code:

browser.find_element_by_class_name("btn blue trustdevice trustbtn").click()

I receive this error selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".btn blue trustdevice trustbtn"}

I also tried

elements = browser.find_element_by_class_name("btn blue trustdevice trustbtn")
for e in elements:
e.click()

but received the same error. Please let me know if any more info is required!

EDIT:

button = browser.find_element_by_class_name("btn blue trustdevice trustbtn")

gives me the same error message as well.

find_element_by_class_name() only accept single classname. Instead use css selector.

Induce WebDriverWait() and wait for element_to_be_clickable()

You can use either of locator.

Css Selector:

WebDriverWait(browser,10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,".btn.blue.trustdevice.trustbtn"))).click()

OR

Xpath:

WebDriverWait(browser,10).until(EC.element_to_be_clickable((By.XPATH,"//button[./span[text()='Trust']]"))).click()

You need to import below libraries.

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

It's a common issue that people tend to forget that you have to add some time.sleep() between your clicks to let the page load. So i would suggest to add:

import time

# action

time.sleep(5) #wait 5 seconds

# next action

Also you can use seleniums waits:

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

driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"))
    )
finally:
    driver.quit()
