I updated the lecture order :) Thank you for your feedback and I'll see you in the practical part! In addition, there are 3 solutions below to prevent the window from closing ^^ 1. Keep the running state using Jupyter Notebook. -> Refer to the YouTube video below https://youtu.be/1tKPqQmXM98 2. Add an option to prevent closing. (detach) from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.chrome.options import Options # Prevent browser shutdown options chrome_options = Options() chrome_options.add_experimental_option("detach", True) driver = webdriver.Chrome("c://chromedriver.exe", options=chrome_options) # Move to the corresponding webpage address driver.get("https://www.naver.com") -> Refer to the YouTube video below https://youtu.be/LoPvjfABlBA 3. Prevent forced termination using an infinite loop or input() Insert the input() command at the end of the code so that the program does not terminate until the user input is received.
