Selenium关闭多余窗口保留当前窗口

from selenium import webdriver

d1 = webdriver.Chrome()
d1.maximize_window()
d1.get(Firsturl)
#
代码简化了，之后，点击连接打开新的标签页


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)

#
做完一系列操作后关闭school_handle
d1.close()
#切换窗口会第一个窗口
d1.switch_to.window(First_handle)
