How do I click "Copy" using Selenium WebDriver? - python-3.x

Question

How do I click the "Copy" button from this URL https://www.w3resource.com/java-exercises/basic/java-basic-exercise-249.php
The tag I need to click is tagged as "Copy"
I have tried multiple "find element by" methods however I keep getting errors such as no such element.
button = driver.find_elements_by_class_name('toolbar-item') #not working
driver.findElementByClassName("a.cc_btn.cc_btn_accept_all") #not working
driver.find_element_by_css_selector("toolbar").click() #not working
driver.findElementByClassName("toolbar-item").click() #not working
In this case how to I select the "Copy" ref and what method is used to click "Copy"?
Further, when the "Copy" button is clicked, how can I paste the contents to a text file.
These are the other errors I get.
Errors:

To click on the Copy button induce WebDriverWait() and wait for presence_of_element_located() and following xpath.You need to scroll the element to click.
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
driver = webdriver.Chrome()
driver.get("https://www.w3resource.com/java-exercises/basic/java-basic-exercise-249.php")
copybtn=WebDriverWait(driver,15).until(EC.presence_of_element_located((By.XPATH,"//a[text()='Copy']")))
copybtn.location_once_scrolled_into_view
copybtn.click()
You can use following css selector as well.
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
driver = webdriver.Chrome()
driver.get("https://www.w3resource.com/java-exercises/basic/java-basic-exercise-249.php")
copybtn=WebDriverWait(driver,5).until(EC.presence_of_element_located((By.CSS_SELECTOR,".toolbar-item>a")))
driver.execute_script("arguments[0].scrollIntoView();", copybtn)
copybtn.click()
