headless error

셀레니움 버전 업데이트에서 다음과 같은 변화를 말함 Selenium 4.3.0 * Deprecated find_element_by_* and find_elements_by_* are now removed (#10712) * Deprecated Opera support has been removed (#10630) * Fully upgraded from python 2x to 3.7 syntax and features (#10647) * Added a devtools version fallback mechanism to look for an older version when mismatch occurs (#10749) * Better support for co-operative multi inheritance by utilising super() throughout * Improved type hints throughout 따라서 강의에서 언급한 "find_element_by_tag_name"코드는 이제 지원하지 않음. find_element("tag name", "h1") 이 코드를 사용하면 원하는 결과를 얻을 수 있음. 셀레니움 변경사항은 링크 참고. https://github.com/SeleniumHQ/selenium/blob/a4995e2c096239b42c373f26498a6c9bb4f2b3e7/py/CHANGES
