我正在計數google主頁上的單詞。但是我在初始階段得到了AttributeError。Python-AttributeError:'NoneType'對象沒有屬性'lower'
我的代碼 - >
import requests
from bs4 import BeautifulSoup
import operator
def main(url):
word_list=[]
source_code=requests.get(url).text
soup=BeautifulSoup(source_code,'lxml')
for post_text in soup.findAll('a'):
content=post_text.string
words=content.lower().split()
for each_word in words:
print(each_word)
word_list.append(each_word)
main('https://www.google.co.in/?gfe_rd=cr&dcr=0&ei=2-nqWavnB4WN8Qf4n7eQAw')
我的輸出是 - >
images
maps
play
youtube
news
gmail
drive
Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'lower'
您需要添加一個'如果內容後'含量= POST_TEXT不None'。字符串「,因爲所有'a'標籤都不需要文本字符串。 – ZdaR
