The multi-window switch selenium python

premise:

During the operation page sometimes click a link will pop up a new window, which requires the host to the switch on a newly opened window. Providing WebDriver switch_to.window () method may be implemented to switch between different windows. 

content:

In Baidu, for example, switching between the two windows:

from Selenium the webdriver Import 
Import Time 

Driver = webdriver.Chrome () 
driver.implicitly_wait ( 10 ) 
Driver. GET ( " http://www.baidu.com " ) 

# Baidu search window obtained 
sreach_windows = driver.current_window_handle 

driver.find_element_by_link_text ( ' Login ' ) .click () 
driver.find_element_by_link_text ( " Register Now " ) .click () 

# get all currently open window handle 
all_handles = driver.window_handles 

# to enter the registration window 
for handle in all_handles:
    if handle != sreach_windows:
        driver.switch_to.window(handle)
        print('now register window!')
        driver.find_element_by_name("account").send_keys('username')
        driver.find_element_by_name('password').send_keys('password')
        time.sleep(2)
  
driver.quit()

Is to first save the current window tag, then kept behind open windows to circulate, to jump to the window you want.
