python and selenium trows exception on get_attribute on iframe

As I want to test some cookies accept code, i get an exception while working with get_attribute..

Here is my Code so far:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager
from time import sleep
import random
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

chrome_options = webdriver.ChromeOptions()
    chrome_options.add_experimental_option('excludeSwitches', ['enable-logging'])
chrome_options.add_experimental_option("detach", True)

driver = webdriver.Chrome(options=chrome_options)
driver.get("https://www.golem.de")
sleep(random.randrange(5,7))

print(f"URL: {driver.current_url}")

iframes = driver.find_elements(By.TAG_NAME, "iframe")

for iframe in iframes:
    driver.switch_to.frame(iframe)
    print(f"URL: {driver.current_url}")
    
    print(dir(iframe))
    iframe_attributes = iframe.get_attribute('name')
    #print(dir(iframe_attributes)
    try:
        button = driver.find_element(By.XPATH, "//button[text()='Zustimmen und weiter']")
        button.click()
        break
    except:
        driver.switch_to.default_content()

This is console output:

Traceback (most recent call last):
  File "C:DATAtest_code.py", line 31, in <module>
    iframe_attributes = iframe.get_attribute('name')

It seems that iframe has the get_attribute method, but throws nevertheless an error, when using the get_attribute method on it.
Can you help me?

PS: The reason the code is, to accept the cookies. Without the iframe loop i could not access the button, thatswhy the loop into the iframe.
Thanks in advance.
