修改好了

with open("tmp/ztree.csv", "a") as csvfile:
writer = csv.writer(csvfile)
for num,e in enumerate(elementList,start=1):
writer.writerow([e.text])
try:
print(num)
print(e.get_attribute('innerHTML'))
e.find_element_by_class_name('center_close').click()
time.sleep(2)
#print(eparent)
#eparent.click()
except WebDriverException:
print("Element is not clickable")

print(e.text)

下面要改成递归方法和叫错
