Selenium關閉多餘窗口保留當前窗口

from selenium import webdriver

d1 = webdriver.Chrome()
d1.maximize_window()
d1.get(Firsturl)
#
代碼簡化了，之後，點擊連接打開新的標籤頁


First_handle = d1.current_window_handle
n = d1.window_handles
print (n)
school_handle = None
for handle in n:
    if handle != First_handle:
        school_handle = handle

d1.switch_to.window(school_handle)

#
做完一系列操作後關閉school_handle
d1.close()
#切換窗口會第一個窗口
d1.switch_to.window(First_handle)
