获取 NameError：名称“团队”未使用 Selenium Python 定义

Question

我尝试抓取一个 gemble 网站，当我删除打印代码时，我没有得到输出（过程以退出代码 0 结束）我不知道问题可能是什么

这是代码 -> 从硒导入网络驱动程序 从 selenium.webdriver.chrome.options 导入选项

options = Options()
options.headless = False
web = 'https://fezbet1.com/en/sport?sportids=1'
path = r'C:\Users\Senne\Desktop\Chromedriver\chromedriver.exe'

options.add_argument('window-size=1920x1080')
driver = webdriver.Chrome(path, options=options)
driver.get(web)
driver.maximize_window()

driver.implicitly_wait(10)

frame_ref = driver.find_elements_by_tag_name("iframe")[1]
iframe = driver.switch_to.frame(frame_ref)

box = driver.find_elements_by_class_name('asb-flex-col.asb-cut.asb-pos-wide._asb_events-table-row ')

for data in box :
    teams = data.find_element_by_xpath('.//*[@id="sb"]/div[2]/div[2]/div[2]/div[3]/div/div[1]/div/div[2]/div[1]/div/div/div[2]/div[1]/div/div[2]/div/div/div[2]/div[1]').text
    odds = data.find_element_by_xpath('.//*[@id="sb"]/div[2]/div[2]/div[2]/div[3]/div/div[1]/div/div[2]/div[1]/div/div/div[2]/div[2]/div[1]/div[1]/div/div[2]/div').text

print(teams,odds)

错误说=

Traceback (most recent call last):
  File "C:\Users\Senne\PycharmProjects\webscrapin\main.py", line 25, in <module>
print(teams,odds)
NameError: name 'teams' is not defined

Process finished with exit code 1

Answer 1

您正在尝试定位对象框（使用 class_name），但对象不在 DOM 上。尝试在box = driver.find_elements_by_class_name('asb-flex-col.asb-cut.asb-pos-wide._asb_events-table-row ') 之前使用sleep(5) 添加隐式等待。 您收到此错误是因为该框为空。

Answer 2

我做了一些更改，这是更新后的代码：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import pandas as pd

options = Options()
options.headless = False
web = 'https://fezbet1.com/en/sport?sportids=1'
path = r'C:\Users\Senne\Desktop\Chromedriver\chromedriver.exe'

options.add_argument('window-size=1920x1080')
driver = webdriver.Chrome(path, options=options)
driver.get(web)
driver.maximize_window()

frame_ref = driver.find_elements_by_tag_name("iframe")[1]
iframe = driver.switch_to.frame(frame_ref)

driver.implicitly_wait(5)

box = driver.find_elements_by_class_name('asb-flex-col.asb-cut.asb-pos-wide._asb_events-table-row ')

Data_list = []

for data in box :
    teams = data.find_element_by_xpath('.//*[@id="sb"]/div[2]/div[2]/div[2]/div[3]/div/div[1]/div/div[2]/div[1]/div/div/div[2]/div[1]/div/div[2]/div/div/div[2]/div[1]').text
    odds = data.find_element_by_xpath('.//*[@id="sb"]/div[2]/div[2]/div[2]/div[3]/div/div[1]/div/div[2]/div[1]/div/div/div[2]/div[2]/div[1]/div[1]/div/div[2]/div').text
    data_items = {
        'teams' : teams,
        'odds' : odds,
    }

    Data_list.append(data_items)

df = pd.DataFrame(Data_list)
print(df)

我现在得到的输出只是=

Empty DataFrame
Columns: []
Index: []
