[英]How to count the number of times a word appears for specific fields using python?
[英]How to find a specific word in multiple webpages or urls and count it, using Python
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))
如何更改我的代码以解析多个 URL 并计算特定单词出现的次数?
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

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))
