selenium用css定位元素，已经打印输出之后又报错说找不到元素

Question

用selenium爬取数据css定位元素也没问题，都正常打印输出了，然后又报错说找不到元素
我也添加等待时间了，元素也不在frame中，希望指点一下

from selenium.webdriver import Chrome
import time
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
import pandas as pd

web = Chrome()  # 实例化一个浏览器对象

url = "https://www.zhipin.com/?ka=header-home"
web.get(url)
web.maximize_window()
web.implicitly_wait(10)
# time.sleep(3)

data = {
    '职位名称': [],
    '工作地址': [],
    '岗位薪资': [],
    '经验要求': [],
    '公司名称': [],
    '公司规模': [],
    '技能要求': [],
    '公司福利': []
}

# 通过css选择器定位元素
web.find_element(By.CSS_SELECTOR, '.ipt-search').send_keys('数据分析', Keys.ENTER)

web.implicitly_wait(30)  # 隐式等待 等浏览器数据加载完成后 就进行下一步操作
# time.sleep(3)


def get_job_info():
    li_list = web.find_elements(By.CSS_SELECTOR, '.job-list-box li')
    for li in li_list:
        job_name = li.find_element(By.CSS_SELECTOR, '.job-name').text
        job_address = li.find_element(By.CSS_SELECTOR, '.job-area').text
        price = li.find_element(By.CSS_SELECTOR, '.salary').text
        yaoqiu = li.find_element(By.CSS_SELECTOR, '.job-info .tag-list').text
        company_name = li.find_element(By.CSS_SELECTOR, '.company-info .company-name a').text
        # company_type = li.find_element(By.CSS_SELECTOR, '.company-info ul li:nth-child(1)').text
        # company_rongzi = li.find_element(By.CSS_SELECTOR, '.company-info ul li:nth-child(2)').text
        company_size = li.find_element(By.CSS_SELECTOR, '.company-info ul li:nth-child(3)').text
        job_skill = li.find_element(By.CSS_SELECTOR, '.job-card-footer .tag-list').text
        fuli = li.find_element(By.CSS_SELECTOR, '.info-desc').text
        print(job_name, job_address, price, yaoqiu, company_name, company_size, job_skill, fuli, sep='|')

        data['职位名称'].append(job_name)
        data['工作地址'].append(job_address)
        data['岗位薪资'].append(price)
        data['经验要求'].append(yaoqiu)
        data['公司名称'].append(company_name)
        data['公司规模'].append(company_size)
        data['技能要求'].append(job_skill)
        data['公司福利'].append(fuli)
        df = pd.DataFrame(data)
        df.to_excel('SF.xlsx', index=False)
    web.find_element(By.CSS_SELECTOR, '.ui-icon-arrow-right').click()


for i in range(3):
    print(f'正在获取第{i}页数据')
    web.implicitly_wait(30)
    # time.sleep(5)
    get_job_info()

web.quit()  # 自动关闭浏览器
print("爬取完毕！")

这个问题可能是因为第一个元素有这个class能找到，第二个没有所以报错了，具体情况看一页面
