python - 使用 BeautifulSoup 抓取 Google 搜索

Question

我想抓取 Google 搜索的多个页面。到目前为止，我只能抓取第一页，但如何才能抓取多个页面。

from bs4 import BeautifulSoup
import requests
import urllib.request
import re
from collections import Counter

def search(query):
    url = "http://www.google.com/search?q="+query

    text = []
    final_text = []

    source_code = requests.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text,"html.parser")

    for desc in soup.find_all("span",{"class":"st"}):
        text.append(desc.text)

    for title in soup.find_all("h3",attrs={"class":"r"}):
        text.append(title.text)

    for string in text:
        string  = re.sub("[^A-Za-z ]","",string)
        final_text.append(string)

    count_text = ' '.join(final_text)
    res = Counter(count_text.split())

    keyword_Count = dict(sorted(res.items(), key=lambda x: (-x[1], x[0])))

    for x,y in keyword_Count.items():
        print(x ," : ",y)


search("girl")
