web = webdriver.Chrome()

web.get("http://lagou.com")

# 找到某个元素,点击它

el = web.find_element(By.XPATH, '//*[@id="changeCityBox"]/p[1]/a')

el.click()  #点击事件

#time.sleep(1)   #有时,要让浏览器缓一会儿

#找到输入框, => 输入回车/点击搜索按钮
web.find_element(By.XPATH, '//*[@id="search_input"]').send_keys("python", Keys.ENTER)

因为页面还没有完成加载出来，所以用 time.sleep 让它等待页面完全加载

import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys

web = webdriver.Chrome("chromedriver.exe")

web.get("http://lagou.com")

# 找到某个元素,点击它

el = web.find_element(By.XPATH, '//*[@id="changeCityBox"]/p[1]/a')

el.click()  #点击事件

#time.sleep(1)   #有时,要让浏览器缓一会儿

#找到输入框, => 输入回车/点击搜索按钮
web.find_element(By.XPATH, '//*[@id="search_input"]').send_keys("python", Keys.ENTER)

#查找存放数据的位置。进行数据提取
#找到页面中存放数据的所有的div
time.sleep(0.1)                                                                                                 # 加了这行
item__10RTO = web.find_elements(By.XPATH, '//*[@id="jobList"]/div[1]/div')
for item in item__10RTO:
    name = item.find_element(By.TAG_NAME, "a").text
    #condition = item__10RTO = web.find_element(By.XPATH, './div/div/div[1]')
    #wages = item.find_element(By.XPATH, './div/div/div[2]/span')
    print(name)

time.sleep(6000)
