Question

程序从网站获取标题列表。然后存储在变量（listOfjobs）中。我希望能够将该变量的内容（作业位置列表）写入现有文本文件，但它告诉我只接受字符串。如何在文本文件中将listOfJobs的值打印输出为纯文本？谢谢！

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('https://jobs.theguardian.com/searchjobs/?LocationId=1500&keywords=personal+assistant&radialtown=London+(Central)%2c+London+(Greater)&countrycode=GB')

elem = browser.find_elements_by_class_name('lister__header')

for el in elem:                 
   listOfJobs = print(el.text)
    print(listOfJobs)


import os
helloFile = open('C:\\Users\\sk\\PycharmProjects\\test\\test_email.txt', 'w')
helloFile.write(websiteText)
helloFile.close()

Answer 1

以字符串形式附加到文件列表：

'\n'.join(str(el) for el in listOfjobs)

最好使用上下文管理器进行文件处理：

with open('C:\\Users\\sk\\PycharmProjects\\test\\test_email.txt', 'a') as res:
    res.write(''.join(str(el) for el in listOfjobs))

Answer 2

每次运行代码时都需要打开a才能追加，w会覆盖：

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('https://jobs.theguardian.com/searchjobs/?LocationId=1500&keywords=personal+assistant&radialtown=London+(Central)%2c+London+(Greater)&countrycode=GB')

elem = browser.find_elements_by_class_name('lister__header')


with open('C:\\Users\\sk\\PycharmProjects\\test\\test_email.txt', "a") as f:
    for el in elem:                 
       f.write(el.text+"\n")

Python：将变量结果打包为文本以将其附加到文本文件
