셀레니움에서 dwebdriver.find_element_by_class_name 함수를 사용하려고 했으나 아래와 같은 에러가 발생했다.

     12     print(search_box)

AttributeError: 'WebDriver' object has no attribute 'find_element_by_class_name'

 

해결 방법

selenium 4는 find_element_by... 시리즈를 find_element 함수로 통일했다. 

따라서 find_element_by_class_name이 아니라 find_element(By.CLASS_NAME, "class_name")으로 바꿔주면 해결된다. 

page_num = 2
url = f"https://tomatolife.tistory.com/{page_num}"

driver = webdriver.Chrome(executable_path="chromedriver")
driver.get(url=url)

try:
    element = WebDriverWait(driver, 5).until(
        EC.presence_of_element_located((By.CLASS_NAME, "contents_style"))
    )
    search_box = driver.find_element(By.CLASS_NAME, "contents_style")
    print(search_box)
finally:
    driver.quit()
