python, 取不出元素

Question

from selenium import webdriver
dri = webdriver.Chrome()
dri.get("https://www.zhipin.com/web/geek/job?city=101020100%22%22)
dri.find_element_by_css_selector(".input")
print(dri.find_element_by_css_selector(".input"))

为什么取不出来元素呢?

原因
模拟页面打开需要一定时间，需要设置一个等待时间再进行下一步操作

解决方法
设置等待时间

代码如下：

from selenium import webdriver
import time

dri = webdriver.Chrome()
dri.get("https://www.zhipin.com/web/geek/job?city=101020100%22%22)
time.sleep(10)

print(driver.title)
dri.find_element_by_css_selector(".input")
print(dri.find_element_by_css_selector(".input"))
