Question

下面是我的代码。请检查并纠正我。

import requests

from bs4 import BeautifulSoup

url = ["https://www.tensorflow.org/","https://www.tomordonez.com/"]

the_word = input()

r = requests.get(url, allow_redirects=False)

soup = BeautifulSoup(r.content, 'lxml')

words = soup.find(text=lambda text: text and the_word in text)

print(words)

count = len(words)

print('\nUrl: {}\ncontains {} of word: {}'.format(url, count, the_word))

如何更改代码以解析多个URL并计算特定单词出现了多少次？

Answer 1

import requests
from bs4 import BeautifulSoup

url_list = ["https://www.tensorflow.org/","https://www.tomordonez.com/"]

#the_word = input()
the_word = 'Python'

total_words = []
for url in url_list:
    r = requests.get(url, allow_redirects=False)
    soup = BeautifulSoup(r.content.lower(), 'lxml')
    words = soup.find_all(text=lambda text: text and the_word.lower() in text)
    count = len(words)
    words_list = [ ele.strip() for ele in words ]
    for word in words:
        total_words.append(word.strip())

    print('\nUrl: {}\ncontains {} of word: {}'.format(url, count, the_word))
    print(words_list)


#print(total_words)
total_count = len(total_words)

输出：

Url: https://www.tensorflow.org/
contains 0 of word: Python
[]

Url: https://www.tomordonez.com/
contains 8 of word: Python
['web scraping with python', 'this is a tutorial on web scraping with python. learn to scrape websites with python and beautifulsoup.', 'python unit testing tutorial', 'this is a tutorial about unit testing in python.', 'pip install ssl module in python is not available', 'troubleshooting ssl module in python is not available', 'python context manager', 'a short tutorial about python context manager: "with" statement.']

您可以使用re模块来查找特定文本。

import requests
import re
from bs4 import BeautifulSoup

urls = ["https://www.tensorflow.org/","https://www.tomordonez.com/"]

the_word ='Tableau'

for url in urls:
 print(url)
 r = requests.get(url, allow_redirects=False)
 soup = BeautifulSoup(r.text, 'html.parser')
 words = soup.find_all(text=re.compile(the_word))
 print(len(words))
