python selenium selenium-webdriver webdriver findelement

find_element_by_* commands are deprecated in Selenium

When starting the function

def run(driver_path):
    driver = webdriver.Chrome(executable_path=driver_path)
    driver.get('https://tproger.ru/quiz/real-programmer/')
    button = driver.find_element_by_class_name("quiz_button")
    button.click()
run(driver_path)

I'm getting errors like these:

<ipython-input-27-c5a7960e105f>:6: DeprecationWarning: executable_path has been deprecated, please pass in a Service object
  driver = webdriver.Chrome(executable_path=driver_path)
<ipython-input-27-c5a7960e105f>:10: DeprecationWarning: find_element_by_* commands are deprecated. Please use find_element() instead
  button = driver.find_element_by_class_name("quiz_button")

but I can't understand why.

I'm using WebDriver at the latest version for my Chrome's version. I don't why I get

find_element_by_* commands are deprecated

when it's in the documentation that the command exists.

Solution

This error message:

DeprecationWarning: find_element_by_* commands are deprecated. Please use find_element() instead

implies that the find_element_by_* commands are deprecated in the latest Selenium Python libraries.

As AutomatedTester mentions: This DeprecationWarning was the reflection of the changes made with respect to the decision to simplify the APIs across the languages and this does that.

Solution

Instead you have to use find_element(). As an example:

You have to include the following imports
from selenium.webdriver.common.by import By

Using class_name:

button = driver.find_element_by_class_name("quiz_button")

Needs be replaced with:

button = driver.find_element(By.CLASS_NAME, "quiz_button")

Along the lines of, you also have to change the following:

Using id:

element = find_element_by_id("element_id")

Needs be replaced with:

element = driver.find_element(By.ID, "element_id")

Using name:

element = find_element_by_name("element_name")

Needs be replaced with:

element = driver.find_element(By.NAME, "element_name")

Using link_text:

element = find_element_by_link_text("element_link_text")

Needs be replaced with:

element = driver.find_element(By.LINK_TEXT, "element_link_text")

Using partial_link_text:

element = find_element_by_partial_link_text("element_partial_link_text")

Needs be replaced with:

element = driver.find_element(By.PARTIAL_LINK_TEXT, "element_partial_link_text")

Using tag_name:

element = find_element_by_tag_name("element_tag_name")

Needs be replaced with:

element = driver.find_element(By.TAG_NAME, "element_tag_name")

Using css_selector:

element = find_element_by_css_selector("element_css_selector")

Needs be replaced with:

element = driver.find_element(By.CSS_SELECTOR, "element_css_selector")

Using xpath:

element = find_element_by_xpath("element_xpath")

Needs be replaced with:

element = driver.find_element(By.XPATH, "element_xpath")

Note: If you are searching and replacing to implement the above changes, you will need to do the same thing for find_elements_*, i.e., the plural forms of find_element_*.
