I've Got Invalidargumentexception When I Used Switch_to.window By Selenium / Python

I've seen many example script on how to use selenium switch_to.window Here is an example script regarding what I learned, doesn't work at all: from selenium import webdriver

Solution 1:

Forgot about webdriver chrome/firefox - better use webdriver_manager which manages the latest browsers with your python version More about webdriver_manager can be found here

pip install webdriver_manager

here is the flawlessly code

from webdriver_manager.firefox import GeckoDriverManager
from selenium import webdriver

browser = webdriver.Firefox(executable_path=GeckoDriverManager().install())

script = """
        myWindow = window.open("", "ChildWindow", "width=200,height=100");
    """
browser.execute_script(script)

wHandles = browser.window_handles
print(wHandles)

handle = wHandles[1]
print(handle, type(handle))

browser.switch_to.window(handle)

browser.quit()
