How to switch to new window in Selenium for Python?

You can do it by using window_handles and switch_to_window method.

Before clicking the link first store the window handle as

window_before = driver.window_handles[0]

after clicking the link store the window handle of newly opened window as

window_after = driver.window_handles[1]

then execute the switch to window method to move to newly opened window

driver.switch_to_window(window_after)

and similarly you can switch between old and new window. Following is the code example

import unittestfrom selenium import webdriverclass GoogleOrgSearch(unittest.TestCase):    def setUp(self):        self.driver = webdriver.Firefox()    def test_google_search_page(self):        driver = self.driver        driver.get("http://www.cdot.in")        window_before = driver.window_handles[0]        print window_before        driver.find_element_by_xpath("//a[@href='http://www.cdot.in/home.htm']").click()        window_after = driver.window_handles[1]        driver.switch_to_window(window_after)        print window_after        driver.find_element_by_link_text("ATM").click()        driver.switch_to_window(window_before)    def tearDown(self):        self.driver.close()if __name__ == "__main__":    unittest.main()

On top of the answers already given, to open a new tab the javascript command window.open() can be used.

For example:

# Opens a new tabself.driver.execute_script("window.open()")# Switch to the newly opened tabself.driver.switch_to.window(self.driver.window_handles[1])# Navigate to new URL in new tabself.driver.get("https://google.com")# Run other commands in the new tab here

You're then able to close the original tab as follows

# Switch to original tabself.driver.switch_to.window(self.driver.window_handles[0])# Close original tabself.driver.close()# Switch back to newly opened tab, which is now in position 0self.driver.switch_to.window(self.driver.window_handles[0])

Or close the newly opened tab

# Close current tabself.driver.close()# Switch back to original tabself.driver.switch_to.window(self.driver.window_handles[0])

Hope this helps.

window_handles should give you the references to all open windows.

this is what the documentation has to say about switching windows.
