寫入.txt文件Python時發生TypeError

Question

我正在從網站上獲取數據，並將其寫入.txt文件。

head = 'mpg123 -q '
tail = ' &'

url = 'http://www.ndtv.com/article/list/top-stories/'
r = requests.get(url)
soup = BeautifulSoup(r.content)

g_data = soup.find_all("div",{"class":"nstory_intro"})
log = open("/home/pi/logs/newslog.txt","w")
soup = BeautifulSoup(g_data)

# Will grab data from website, and write it to .txt file
for item in g_data:
        shorts = textwrap.wrap(item.text, 100)
        text_file = open("Output.txt", "w")
        text_file.write("%s" % g_data)

        print 'Wrote Data Locally On Pi'
        text_file.close()

        for sentance in shorts:
                print 'End.'
    #               text_file = open("Output.txt", "w")
    #               text_file.close()

我知道網站會提取正確的信息，但是，當我在控制台中運行它時，我總是收到此錯誤消息：

TypeError: 'ResultSet' does not have the buffer interface

我嘗試在Google上四處查看，對於TypeError: 'str' does not have the buffer interface字符串，我TypeError: 'str' does not have the buffer interface看到它TypeError: 'str' does not have the buffer interface在Python 2.x和Python 3.x之間TypeError: 'str' does not have the buffer interface 。 我嘗試在代碼中實現其中的一些解決方案，但它仍然不斷出現'ResultSet'錯誤。

ResultSet是您的g_data類型：

In [8]: g_data = soup.find_all('div',{'class':'nstory_intro'})

In [9]: type(g_data)
Out[9]: bs4.element.ResultSet

您最好使用上下文管理器來自動處理打開和關閉。

如果只想將g_data文本內容寫入Output.txt ，則應執行以下操作：

with open('Output.txt', 'w') as f:
    for item in g_data:
        f.write(item.text + '\n')
