Python Selenium将数据存储到CSV中的特定列？

我有两个打印文件，我想将它们写入到一个CSV文件中，分别写入列a和列B

我的问题是，当我在末尾同时打印（第一次和第二次打印）时，我只得到一个元素，我猜是多次，因为它不在循环中。在

print((text), (link[0:-9]))

结果：

^{pr2}$

我的第一次打印是这样的：我想把它打印到列A

PWFERT-BK
PMFEP-BK
LMF8CC-BL
PMFEP-GY
ASPCP-NV
LWBASK-PK
LWBATA-PK
LWBATOP-PK
LMF8CC-RD

我的第二次打印是这样的：我想把它打印到列B

LMFCIIC


LWBASK
LWBATA
LWBATOP
LMFCIIC

以下是我的完整代码：

from bs4 import BeautifulSoup
from selenium import webdriver
import html5lib
import time
import requests

driver_path = '/usr/local/bin/chromedriver 2'
driver = webdriver.Chrome(driver_path)
driver.implicitly_wait(10)

driver.get('https://www.tenniswarehouse-europe.com/zzz/producttracker_bl.html?ccode=SWIMG030')
try:
    iframe = driver.find_elements_by_tag_name('iframe')
    for i in range(0, len(iframe)):
            f = driver.find_elements_by_tag_name('iframe')[i]
            driver.switch_to.frame(i)
            #  your work to extract link
            text = driver.find_element_by_tag_name('body').text
            text = text.replace("Code: ","")
            text = text.replace("No Copy Images to TW Server","")
            print(text)
            driver.switch_to_default_content()
finally:
    driver.quit()

resp = requests.get('https://www.tenniswarehouse-europe.com/zzz/producttracker_bl.html?ccode=SWIMG030')
soup = BeautifulSoup(resp.text,"lxml")
for frame in soup.findAll('img'):
    link = (frame['src'])
    link = link.split('=')[1] 
    print ((link[0:-9]))
  • 我用了www.example.com网站因为无法从我的网络中访问链接

当您编写driver.switch_to.frame(i)时，您基本上是在访问iframe html元素。像普通的html页面一样，您也可以访问它的内部元素。在

从你之前的问题来看，iframe就像

<body>
<a href="http://www.test2.com" target="_blank">
<img src="https://img2.test2.com/LWBAD-1.jpg"></a>
<br/>Code: LWBAD

您可以通过

^{pr2}$

并将其存储在csv文件中

代码：

from bs4 import BeautifulSoup
from selenium import webdriver
import html5lib
import time
import requests
import csv

driver_path = '/usr/local/bin/chromedriver 2'
driver = webdriver.Chrome(driver_path)
driver.implicitly_wait(10)

driver.get('https://www.example.com')

iframe = driver.find_elements_by_tag_name('iframe')
images = driver.find_elements_by_tag_name('img')
with open('file_name.csv', 'w', newline='') as csvfile:
    field_names = ['text', 'src']
    writer = csv.DictWriter(csvfile, fieldnames=field_names)
    writer.writerow({'text': 'text', 'src': 'src'})
    for i in range(0, len(iframe)):
        f = driver.find_elements_by_tag_name('iframe')[i]
        img_src = images[i].get_attribute('src')

        # do the src splitting here
        img_src = img_src.split('=')[1]

        driver.switch_to.frame(i)

        text = driver.find_element_by_tag_name('body').text


        text = text.replace("Code: ", "")
        text = text.replace("No Copy Images to TW Server", "")
        print(text)
        writer.writerow({'text': text, 'src': img_src})

        driver.switch_to_default_content()
driver.quit()
